Based on high-power, low-noise thulium-doped fiber amplification and frequency tripling technology, high-power narrow-linewidth laser output with any central wavelength in the range of 578nm is achieved.
A thulium-doped fiber DFB laser is frequency-doubled, then sum frequency generated with a erbium-doped fiber laser to produce high-power narrow-linewidth laser output.。
Based on high-power, low-noise raman fiber lasers amplifier and frequency doubling technology, Precilasers can provide high-power, narrow linewidth laser output at 578nm
