Single Pass DFG Fiber Laser 2.4-4 um
PreciLasers offers a single pass SDFG fiber laser , which uses ultra-narrow linewidth fiber DFB laser as seeds, all fiber amplifiers to boost the output power and single pass PPLN DFG module to get high power mid-infrared laser output. The DFG fiber laser could cover the output wavelengths from 2400 to 4000 nm, with narrow linewidth (less than 200 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.
