Product introduction:
Shanghai Hanyu 1550 nm and 1064 nm band narrow linewidth single frequency semiconductor lasers are excellent low noise single frequency laser modules. The output spectral linewidth is less than 5 kHz, with ultra-low phase noise and relative intensity noise (RIN). The output spectral edge-touch rejection ratio is more than 40 dB. Compared with most commercial fiber lasers, CoSF-SC single frequency semiconductor lasers have better performance of Wavelength stability and can better adapt to all kinds of harsh application environment can achieve stable single longitudinal mode output without mode hopping phenomenon under the influence of temperature change, vibration, shock and other external conditions. The output power of 1550nm and 1064nm narrow linewidth single frequency semiconductor lasers is optional from 5mW to 200mW. Products with higher output power can be provided as required.
