Single Emitters
Single Emitters: Laser diode modules based on single emitters.
Wavelengths between 375 nm – 1550 nm are available in a range of power that starts below 1mW and scales up to some watts.
We can add optics, mechanics and electronics to fit customer’s demands.
Fiber-coupled Lasers
Fiber-coupled Lasers
Highly efficient fiber coupled diode lasers with Monocrom Solder-free laser bar Clamping™ technology. The lack of a “smile” effect results in an optimum coupling efficiency to the optical fiber. We also provide wavelength stabilized fiber-coupled laser modules with a grating for wavelength locking. Having a low smile results in an exceptionally well-controlled feedback, which increases the locking efficiency and production repeatability.
For the most demanding applications of high brightness (radiance), we offer fiber-coupled high power diode laser systems capable of delivering 1 kW in power in continuous wave (CW) at a single wavelength.
HiEN Pulse 400-YAG
The HiEN Pulse 400-YAG utilizes a proven Nd:YAG crystal, valued for its high thermal conductivity, mechanical strength, and efficient energy extraction. Its isotropic nature eliminates polarization-related distortions, ensuring stable beam quality and simplified alignment. With excellent resistance to thermal stress and long operational durability, Nd:YAG provides a reliable, high-performance platform for demanding laser applications.
This laser delivers 400 mJ at 1064 nm, with frequency-converted outputs at 532 nm and 355 nm, running at 150 Hz with 10 ns pulses. What distinguishes it most is the remarkable pulse energy stability – RMS fluctuations kept around 1% across all wavelengths. By combining efficient thermal handling with a precisely designed MOPA configuration, the system maintains reliable performance with drift limited to ±1%.
Its smooth super-Gaussian beam profile ensures smooth energy distribution, an essential advantage in nonlinear spectroscopy, OPO and Ti:Sapphire pumping, and precision ablation where uniformity matters most.
A patented solder-free clamping technology extends diode lifetimes to over one billion shots, ensuring stable performance while minimizing service interruptions. This unique design also improves thermal management of the pumping diodes, adding another layer of operational security.
With its modular structure, customizable output, and exceptionally low-maintenance operation, the HiEN Pulse 400-YAG stands as the long-lasting, high-energy nanosecond laser of choice for advanced research and industrial applications.

HiEN Puls 300-YLF
The HiEN Pulse 300-YLF is built utilizing PH6000 pumping module based on Nd:YLF crystal featuring inherently low thermal lensing. This ensures better beam quality, purer polarization, and reduced mechanical stress, making it an excellent choice for high-energy operation regime.
The laser delivers up to 300 mJ at 1053 nm with harmonics at 526.5 nm and 351 nm, operating at 100 Hz with 10 ns pulses. Beyond these numbers, what truly sets it apart is its exceptional pulse energy stability – RMS values in a range of 1 % across all outputs. Thanks to reduced thermal load and a carefully engineered MOPA architecture, performance remains consistent with long-term drift under ±1 %.
The smooth super-Gaussian beam profile provides uniform energy distribution, which directly enhances outcomes in non-linear spectroscopy, OPO, Ti:Sapphire, or dye laser pumping, and material ablation where precision and homogeneity are critical.
