Single Pass SFG Fiber Laser 611-724, 811-865 nm

PreciLasers offers a single pass SFG fiber laser (FL-SSFG), which uses ultra-narrow linewidth fiber DFB laser as seeds, all fiber amplifiers to boost the output power and single pass PPLN SFG module to get high power 6xx nm laser output. The SFG fiber laser could cover the output wavelengths from 611 to 655 nm, with narrower linewidth (less than 10 kHz in 100 us integration time) and excellent beam quality (M² <1.1). It remains mode-hopping-free and stable under wide temperature variation and high mechanical vibration, which is great for frequency locking.
