1550nm Pulse Hom Fiber Laser
Kev piav qhia txog khoom
Cov khoom no yog 1.5μm pulsed fiber laser qhov chaw rau tib neeg lub qhov muag kev nyab xeeb tsim los ntawm Lumispot. Cov khoom tuaj yeem tsim cov zis hluav taws xob siab tshaj plaws, nrog rau kev hloov pauv hluav taws xob-optical siab, ASE qis thiab suab nrov tsis sib xws, thiab ntau yam kev ua haujlwm kub. Nws yog qhov tsim nyog rau kev siv ua LiDAR emission lub teeb qhov chaw.
