Crylink's 355nm lasers mainly include 355nm passively Q-switched subnanosecond lasers and 355nm single-frequency solid-state lasers. The 355nm passively Q-switched subnanosecond laser and 355nm single-frequency solid-state laser are mainly used for Doppler wind measurement, underwater imaging and point-cloud imaging lidar. 355nm single-frequency solid-state laser. The single-frequency laser series includes continuous-wave seed sources, continuous-wave amplifiers with frequency doublers and high-energy solid-state lasers. Nonplanar ring-cavity technology, resonance detection and external-cavity resonant frequency doubling provide multiband products covering narrow-linewidth seed generation, amplification and nonlinear frequency conversion. Advanced optomechanical and thermal integration and automatic electronic control support reliability and stability. Applications include Doppler wind lidar, laser debris observation and laser remote sensing. Advantages include high spectral performance for fine spectral analysis, high-quality seed injection and power amplification, resonance detection to ensure single-frequency operation of every pulse, and frequency locking and stabilization. High-energy single-frequency solid-state and fiber lasers cover 1064nm, 532nm, 355nm and 1.5um bands. The highly integrated systems are easy to operate and provide real-time monitoring and recording of laser status, fault alarms and self-protection.

Satellite laser ranging, Doppler wind measurement, underwater imaging, precision drilling, laser shock peening and nonlinear frequency conversion. 355nm passively Q-switched subnanosecond laser. The series uses active Q-switching or passive Q-switched microchips to generate subnanosecond pulses with excellent beam quality. Active Q-switching gives output-to-trigger jitter below 1ns; passive microchips give jitter <10μs relative to external triggering. The laser operates independently or as an amplifier seed, and the company's amplifiers can raise energy to tens of mJ. Wavelengths can be extended to 532nm, 355nm and 266nm. Good beam quality, high peak power, reliability, compact size and easy operation and maintenance suit demanding airborne, vehicle-mounted and high/low-temperature environments.
