Er-Doped Single-Pass SHG Fiber Laser 765-798 nm

Precilasers provides narrow-linewidth, mode-hopping free, frequency-doubled single frequency lasers from 765 to 798 nm, based on Er-doped fiber lasers (EFL-SSHG).It consists of an all-fiber amplifier seeded with single frequency fiber DFB laser, and a single-pass frequency doubling unit with PPLN/PPSLT crystal. Compared with frequency-doubled diode laser, the fiber solution has stable configuration, excellent beam quality (M² <1.1), high output power (up to 10 W) and low intensity noise (RIN<0.06% from 10 Hz-10 MHz). It remains mode-hopping-free and stable under wide temperature variation and high mechanical vibration.
