Achieving Clean Pulses (Picosecond) and Stable CW with 1 μm DFB Seed Lasers

25 July 2025

Fiber lasers and solid-state / fiber hybrid lasers using rare earth doped fiber or crystal are expected to be widely used in various industrial applications such as semiconductor inspection equipment, micromachining, LiDAR, etc., due to their compactness and robustness. QD Laser developed and produced 1 μm band wavelength semiconductor DFB (Distributed FeedBack) lasers, which can be used for seed light sources of these lasers, by utilizing crystal growth technology, grating formation technology, and semiconductor laser chip design technology. We will introduce the features of our DFB lasers.
