CoLID-II 1064 nm Short Pulse Fiber Laser for LiDAR and Ranging

The CoLID-II-1064 short pulse fiber laser is a compact, high‑performance 1064 nm source engineered for demanding LiDAR, rangefinding, and 3D sensing applications. Built around a MOPA (Master Oscillator Power Amplifier) architecture and an all‑fiber optimized design, this pulsed laser delivers up to 10 kW peak power, 2 W average power, and pulse energies up to 50 μJ while maintaining near diffraction‑limited beam quality (M² < 1.1). This combination of high peak power and excellent spatial mode makes it particularly well suited for long‑range, high‑resolution optical systems where signal strength and beam quality are critical.

Operating in the 1059–1069 nm band with a nominal center wavelength of 1064 nm, the CoLID-II-1064 offers adjustable pulse widths from 1 ns to 50 ns and a wide repetition rate range from 30 kHz to 500 kHz. The repetition rate is controlled via an external TTL trigger, while pulse duration is easily configured through a computer interface. This flexible timing control enables precise optimization of the energy–resolution trade‑off in different environments, whether the priority is long‑distance detection, fine spatial detail in 3D scanning, or fast sampling for dynamic scenes.

Designed for seamless integration into larger systems, the laser comes in a rugged rectangular module package measuring only 135 mm × 90 mm × 30 mm. An internal high‑quality MCU provides straightforward electronic control and monitoring, simplifying OEM integration into LiDAR engines, rangefinders, and telemetry platforms. The built‑in high‑power optical isolator safeguards the laser from back‑reflections, improving reliability when coupled to external optics or when used in environments with variable feedback conditions. Output is provided via a fiber pigtail with FC/APC connector or an optional collimator, giving system designers flexibility in beam delivery and alignment.

Long‑term operational stability is a core strength of this source. Output power stability is typically within ±2% over 8 hours at 25 °C after warm‑up, ensuring consistent measurement performance over extended runs. With electrical power consumption typically up to 24 W from a 12 V DC supply, the CoLID-II-1064 is well suited for mobile, battery‑powered, or space‑constrained platforms where efficiency matters. Its wide operating temperature range from −35 °C to +65 °C and storage range from −40 °C to +85 °C enable reliable deployment in harsh outdoor conditions common in automotive LiDAR, surveying, and defense‑oriented sensing.

Compared with many pulsed 1064 nm fiber lasers used in LiDAR and ranging, the CoLID-II-1064 stands out for its combination of high peak power, short adjustable pulse widths, and excellent beam quality in a very compact, integrator‑friendly module. The random polarization output, integrated monitoring for synchronization, and TTL trigger compatibility support straightforward interfacing with existing control electronics and detection chains. These characteristics make it an attractive choice for designers developing next‑generation LiDAR units, long‑range laser rangefinders, target detection systems, 3D scanners, and precise optical telemetry solutions where stability, reliability, and long service life translate directly into lower system cost of ownership.

Frequently Asked Questions

What is the CoLID-II-1064 1064nm short pulse fiber laser and what are its key specifications?
The CoLID-II-1064 is a 1064 nm pulsed fiber laser based on a MOPA (Master Oscillator Power Amplifier) architecture, designed for LiDAR, rangefinding, 3D scanning, target detection, and telemetry. It provides high peak power up to 10 kW, pulse energy up to 50 µJ, and average power up to 2 W. The pulse width is adjustable from 1 ns to 50 ns, with a repetition rate range of 30 kHz to 500 kHz. It offers excellent beam quality with M² < 1.1, random polarization, integrated output power monitoring, and a built‑in high‑power isolator for protection. The operating temperature range is -35°C to +65°C, with power consumption up to 24 W from a 12 V DC supply.
How is the CoLID-II-1064 pulsed fiber laser triggered and controlled?
The CoLID-II-1064 uses an external TTL trigger input to define the repetition rate. The repetition frequency of the laser follows the input TTL trigger signal within the specified range of 30–500 kHz. Pulse width is not set via the trigger; instead, it is configured electronically via the laser’s internal MCU using a computer interface supplied by the manufacturer (typically via a GUI or command protocol). Once configured, the chosen pulse width and other parameters are stored, enabling easy integration into automated or embedded systems. This architecture is similar to other LiDAR-oriented 1064 nm MOPA fiber lasers on the market that use external TTL/CMOS triggering for synchronization with scanning or detection electronics.
What output options, fiber interface, and beam delivery configurations are available?
The standard optical interface for the CoLID-II-1064 is a single-mode output fiber (length > 0.3 m) terminated with an FC/APC connector. An optional free‑space collimator (denoted as “Col” in the ordering code) is available for applications requiring a collimated beam instead of a fiber-coupled output, such as free‑space LiDAR or rangefinding. The built-in high-power optical isolator is placed before the output to protect the laser from back‑reflections, which is particularly important when coupling into external optics or scanning systems. This configuration is consistent with similar 1064 nm short‑pulse LiDAR lasers commonly used in industrial and defense sensing platforms.
How do I select the right configuration and interpret the CoLID-II-1064 ordering code?
The ordering code is of the form: CoLID-II-1064-XX-YY-ZZ-FA, where: XX = pulse width in ns (e.g., “02” for 2 ns), YY = repetition rate in kHz (e.g., “200” for 200 kHz), ZZ = peak power in kW (e.g., “04” for 4 kW), and FA indicates FC/APC output (with an optional “Col” variant for collimator output, depending on supplier listing). For example, CoLID-II-1064-02-200-04-FA specifies a 1064 nm pulsed fiber laser with 2 ns pulse width, 200 kHz repetition rate, 4 kW peak power, and FC/APC fiber connector. When choosing parameters, users typically trade off peak power and pulse energy versus repetition rate to match LiDAR range, resolution, and eye‑safety constraints, similar to how other commercial short-pulse 1064 nm LiDAR lasers are configured.
Is the CoLID-II-1064 suitable for LiDAR, range finding, and 3D scanning, and what are the benefits for these applications?
Yes, the CoLID-II-1064 is specifically designed for LiDAR, range finding, target detection, 3D scanning, and telemetry. Its short pulse width (1–50 ns) enables fine range resolution, while the high peak power (up to 10 kW) and pulse energy (up to 50 µJ) provide strong return signals at long distances, comparable to other LiDAR‑grade 1064 nm MOPA fiber lasers. The excellent beam quality (M² < 1.1) allows tight focusing or low‑divergence beams, improving detection sensitivity and spatial resolution. The wide repetition rate range (30–500 kHz) supports both long‑range, low‑PRF measurements and high‑speed, high‑PRF scanning. The rugged, compact module design and wide operating temperature range make it suitable for field‑deployed and mobile LiDAR systems, similar to other industrial and automotive LiDAR laser modules.
What are the environmental, reliability, and stability characteristics of the CoLID-II-1064?
The CoLID-II-1064 is designed as a compact, rugged module with an operating temperature range of -35°C to +65°C and a storage range of -40°C to +85°C, enabling outdoor and harsh‑environment use. The all‑fiber MOPA design and integrated isolator enhance robustness and reduce alignment sensitivity. Typical output power stability is ±2% (maximum ±3%) over 8 hours at 25°C after a 30‑minute warm‑up, comparable to other high‑end 1064 nm pulsed fiber sources used in precision sensing. The module is maintenance‑free under normal operating conditions and engineered for long lifetime, aligning with best‑in‑class pulsed fiber lasers used in industrial LiDAR and rangefinding platforms.
What are the electrical power requirements and mechanical dimensions for system integration?
The CoLID-II-1064 operates from a 12 V DC supply and consumes up to approximately 24 W, depending on output power and operating conditions. This low power consumption is advantageous for battery‑powered or mobile LiDAR and rangefinding systems, and is in line with similar compact 1064 nm fiber laser modules on the market. The module’s mechanical footprint is 135 mm (L) × 90 mm (W) × 30 mm (H), allowing easy installation in space‑constrained instruments, UAV payloads, and vehicle‑mounted systems. An integrated output power monitor is included for synchronization and diagnostics during system integration.
