Kugwiritsa ntchito ma laser a SWIR pachitetezo chamaso

Kugwiritsa ntchito kokhwima kwambiri kwa ma laser a short-wave infrared ndi laser otetezedwa ndi maso.Pali mitundu ingapo ya zida zopangira, zomwe zimagwiritsidwa ntchito kwambiri pama laser am'manja komanso makina owongolera moto okwera pamagalimoto.Laser yomwe imagwiritsidwa ntchito pazinthu izi ndi Raman frequency shift laser laser yokhala ndi kutalika kwa 1.54 μm kapena OPO laser yokhala ndi kutalika kwa 1.57 μm. laser yokhala ndi kutalika kwa 1.57 μm.Chowunikirachi chimagwiritsa ntchito chowunikira champhamvu cha InGaAs/InP.Kuyankha pamlingo wapamwamba wa 1.55 μm ndi dongosolo limodzi la kukula kwake kuposa kuyankha kwa silicon avalanche detector ku 1.06 μm laser, ndipo mphamvu yocheperako yodziwika ndi dongosolo limodzi la kutsika.Kuphatikiza apo, kutsika kwamlengalenga kwa 1.54μm ndi 1.57μm lasers nakonso kumakhala kocheperako kwa ma lasers a 1.06μm.Chifukwa chake, laser rangefinder yotetezedwa ndi maso yokhala ndi mphamvu ya laser pulse ya ma millijoules ochepa mpaka khumi imakhala ndi kutalika kwa makilomita 10 mpaka 20.

M'zaka zaposachedwa, ndi kukula mofulumira kwa erbium-doped CHIKWANGWANI laser ndi erbium galasi laser luso ndi kukula kukhwima kwa ndondomeko, kuwonjezeredwa ndi Mipikisano kugunda chizindikiro processing luso, kumwa kakang'ono CHIKWANGWANI lasers ndi erbium galasi lasers ndi voliyumu ang'onoang'ono, Ubwino ndi mphamvu zidzalowa m'malo pang'onopang'ono Kutengera ndi laser-state laser yokhala ndi voliyumu yayikulu, yapamwamba kwambiri komanso kugwiritsa ntchito mphamvu zambiri kutengera kuwala kwa parametric oscillator, yakhala gwero labwino kwambiri la laser laoteteza maso.

SENSUP's LRF-1550-MR/MR yotetezedwa ndi maso, ngakhale mphamvu ya 1.55 μm fiber laser pulse ndi 1,000 kW yokha, imagwiritsa ntchito njira yoyezera mtunda wa ma pulse (ten-pulse).Kuchuluka kwa kuyeza kwa 2.3 m × 2.3 m chandamale kumafika 15 km@5 Hz, kugwiritsa ntchito mphamvu ndi 7 W okha, ndipo kulemera kwake ndi 840 g.Chithunzi 1 ndi chithunzi cha LRF-1550-MR/MR eye-safe laser rangefinder

Chithunzichi chikuwonetsa LRF-1550-MR/MR+ laser rangefinder ya SENSUP
