Pulsed DPSS Light Sources for Research and OEM

Did You Know?

Diode-pumped solid-state lasers (DPSS) are solid-state lasers made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a laser diode. DPSS lasers are known for their high power density, excellent beam quality, and high efficiency. They are commonly used in industrial settings for laser cutting, welding, and trimming. Additionally, they also find uses in military and aerospace settings. One interesting example is the AN/AQS-20A Mine Hunting System, which utilizes DPSS lasers as a means to detect and classify mines from the sea floor to the surface.

Frequently Asked Questions

A pulsed diode-pumped solid-state (DPSS) laser uses a semiconductor diode as the pump source and a crystalline gain medium (e.g., Nd:YAG, Nd:YVO4) to generate discrete pulses rather than continuous output. Compared with flashlamp-pumped solid-state lasers, pulsed DPSS systems typically offer higher electrical-to-optical efficiency, lower thermal load, better beam quality, and more compact form factors. They are commonly configured for Q-switched or mode-locked operation to achieve nanosecond to picosecond pulse durations.

What Are Pulsed DPSS Light Sources?

Pulsed DPSS (diode-pumped solid-state) light sources use laser diodes to pump a solid-state gain medium, delivering pulsed output at fixed wavelengths with high beam quality and stability. These compact lasers are common in laboratory setups, OEM instruments, and industrial tools where controlled pulse parameters are critical.

On FindLight, Pulsed DPSS products span nanosecond to picosecond regimes, covering fundamental wavelengths such as 1064 nm, 946 nm, 1342 nm, and frequency-converted outputs at 532 nm, 355 nm, 266 nm, and other visible/UV lines.

Typical Specifications of Pulsed DPSS Lasers

Pulsed DPSS modules and systems on this page typically specify:

  • Wavelength: IR (e.g., 1064 nm), visible (e.g., 532 nm), and UV (e.g., 355 nm, 266 nm)
  • Pulse duration: From sub-nanosecond to tens of nanoseconds for most Pulsed DPSS units
  • Repetition rate: Single-shot to MHz, with many models offering adjustable kHz ranges
  • Pulse energy and average power: From microjoules to multi-millijoules per pulse, and milliwatts to multi-watts average power
  • Beam quality: M² close to 1 for many Pulsed DPSS sources, with TEM00 or multimode options
  • Pulse-to-pulse stability: Typically a few percent or better
  • Triggering and control: External trigger inputs, TTL/analog modulation, and digital interfaces

Datasheets often also list divergence, beam diameter, polarization, warm-up time, and expected diode lifetime to help you evaluate long-term performance.

Applications of Pulsed DPSS Lasers

Pulsed DPSS light sources are used in laser marking, micro-machining, lidar, range finding, LIBS, spectroscopy, nonlinear optics, fluorescence excitation, and time-resolved measurements. UV Pulsed DPSS models are well suited for fine feature machining of polymers and semiconductors, while IR and green sources are common in general materials processing and R&D experiments.

Buyer Guidance on FindLight

When selecting a Pulsed DPSS product, compare wavelength, pulse duration, peak power, and repetition rate against your interaction mechanism and material or detector response. Evaluate beam quality, pointing stability, and cooling method (air vs. water) for integration into your optical layout. For OEM design, also consider footprint, electrical requirements, and interface options.
