External Resonant SHG Fiber Laser 532, 589, 420 nm

PreciLasers offers external resonant SHG fiber laser FL-RSHG, 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.

    Main Specification

     

     

     

    PreciLasers offers external resonant SHG fiber laser FA-RSHG-532, which uses ultra-narrow linewidth fiber DFB laser as seed, all fiber Yb-doped amplifier to boost the output power and external resonant SHG cavity to get high power, narrow linewidth, low intensity noise and high efficiency 532 nm laser.
    This laser has the characteristics of large output power, narrow linewidth (Lorentz linewidth <10 kHz), low intensity noise, and has been used in customers' optical lattice experiments.
