Frequently Asked Questions

What is the JenLas D2.8 diode-pumped thin-disk laser and what are its key specifications?
The JenLas D2.8 is a frequency-doubled, diode-pumped thin-disk laser designed as an OEM module for easy integration into higher-level systems. It operates at a green wavelength of 532 nm in continuous-wave (cw) mode with an output power of up to 8 W. Key specs include: laser class 4 (EN 60825‑1), typical beam quality M² ≈ 7 (suitable for coupling into a 100 µm fiber), beam diameter < 2 mm, ellipticity < 1:1.5, and switchable pulse duration from ~1 ms up to cw with amplitude modulation capabilities up to about 20 kHz. The compact laser head measures approximately 110 × 55 × 225 mm and weighs about 2.6 kg. It is diode-pumped, uses thin‑disk technology with frequency doubling, and is thermoelectrically cooled (TEC), so no water cooling is required.
What are the typical applications of the JenLas D2.8 532 nm OEM thin-disk laser?
The JenLas D2.8 8 W 532 nm laser is intended for OEM integration in applications that require a compact, high-brightness green source. Typical uses include medical engineering (e.g., illumination, diagnostics, and pumping of medical solid-state lasers), show and entertainment laser systems, projection and display engineering, pumping of other solid-state lasers, light exposure and curing of plastics and photosensitive materials, and replacement of legacy Argon ion lasers. Its cw green output, moderate M², and fiber-coupling capability make it suitable both as a direct process beam and as a pump source in industrial, scientific, and medical equipment.
How does the JenLas D2.8 thin-disk, diode-pumped, frequency-doubled laser work?
The JenLas D2.8 uses a diode-pumped thin-disk laser architecture combined with intracavity frequency doubling to generate 532 nm green light. High‑power laser diodes pump a thin laser crystal in disk form, providing good thermal management and enabling efficient continuous‑wave operation. The fundamental infrared wavelength generated in the thin‑disk resonator is then frequency‑doubled via a nonlinear crystal to produce the 532 nm output. The system is thermoelectrically cooled (TEC), meaning Peltier elements control the temperature of the disk and diodes, eliminating the need for water cooling. Output can be operated in cw mode or modulated by controlling the diode current, allowing pulse durations from about 1 ms to cw and amplitude modulation up to roughly 20 kHz.
What are the electrical and cooling requirements for operating the JenLas D2.8 laser head?
The JenLas D2.8 laser head is driven by a suitable external power supply that must comply with applicable safety and EMC regulations for the end application. The diode section typically requires about 2 V at around 32 A, with a total input power of ≤ 80 VA for the laser head. The laser uses integrated Peltier (TEC) cooling and does not require any water cooling circuits, chillers, or coolant handling. Heat must be removed via an appropriate mechanical and thermal interface (e.g., mounting to a heat sink or cooled base plate) according to Jenoptik’s installation guidelines. The laser is specified for operation in ambient temperatures from approximately +5 °C to +40 °C, and the user must ensure adequate ventilation and heat dissipation within this range.
Is the JenLas D2.8 suitable for fiber coupling and what beam quality can be expected?
Yes. The JenLas D2.8 is designed so that coupling into a 100 µm core fiber is feasible. The specified typical beam quality is M² ≈ 7, which is adequate for many industrial and medical OEM systems that require fiber-delivered green light at 532 nm. The beam diameter is < 2 mm with ellipticity < 1:1.5, which facilitates coupling into step‑index fibers with appropriate numerical aperture using standard coupling optics. For precise coupling efficiency and fiber type recommendations (core size, NA, connector, and handling of back‑reflections), OEM integrators should consult Jenoptik’s application notes or work with their optics supplier to optimize the fiber coupling design.
What safety considerations and laser class apply to the JenLas D2.8 532 nm laser?
The JenLas D2.8 is classified as a Class 4 laser product under EN 60825‑1:2001 / 2007. This means it can emit hazardous levels of visible and/or invisible laser radiation and can pose a danger to eyes and skin from direct, specular, or even diffuse reflections. Integrators must implement comprehensive laser safety measures, including: enclosing the beam path whenever possible; interlocks and key‑switches in end systems; appropriate beam dumps and shielding; and use of suitable laser safety eyewear rated for 532 nm and the maximum 8 W output. All OEM users should follow local and international laser safety standards, perform a risk assessment on the final machine, and ensure proper labeling, warning signs, and user training.
How does the JenLas D2.8 compare to other 8 W 532 nm OEM lasers and what integration options are available?
Compared with many other 5–10 W 532 nm OEM lasers (including DPSS and frequency‑doubled fiber or solid‑state modules), the JenLas D2.8 offers a compact footprint (110 × 55 × 225 mm), no‑water TEC cooling, and reliable thin‑disk technology, making it attractive for space‑constrained and maintenance‑sensitive systems. Its 8 W cw output at 532 nm, moderate beam quality (M² ~7), and up to 20 kHz amplitude modulation capability position it between high‑brightness single‑mode sources and lower‑cost multimode modules. Typical integration options include direct free‑space use, coupling into 100 µm fibers, or using it as a pump for other solid‑state or nonlinear stages. Because Jenoptik continuously improves its products, OEM customers should contact Jenoptik or authorized distributors for the latest driver, interface, and mechanical integration guidelines tailored to their specific application.
