PreciLasers offers external resonant SHG fiber laser , which uses ultra-narrow linewidth fiber DFB laser as seed, all fiber amplifiers to boost the output power and external resonant SHG cavity to get high power visible or UV lasers. The output laser wavelengths cover from 253 to 795 nm with a SHG efficiency of up to 80% and output power of up to 30W. The product has the properties of high output power, optional narrower linewidth (less than 20 kHz in 100 us integration time), tunable and optional low relative intensity noise.
