Ngwa nke lasers SWIR n'ụdị nchekwa anya

Ngwa kachasị tozuru oke nke laser infrared nke dị mkpụmkpụ bụ njiri anya laser dị mma.Enwere ọtụtụ ụdị nke akụrụngwa ngwaahịa, nke a na-ejikarị maka ụdị laser ejiri aka yana sistemụ njikwa ọkụ na-agbanye ụgbọ ala.Laser eji eme ihe na ngwaahịa ndị a bụ laser ugboro ugboro nke Raman nwere ogologo ogologo nke 1.54 μm ma ọ bụ laser OPO nwere ogologo ogologo nke 1.57 μm. Laser a na-eji na ngwaahịa ndị a bụ Laser na-agbanwe ugboro ugboro nke Raman nwere ogologo nke 1.54 μm ma ọ bụ OPO. laser nwere ogologo ogologo nke 1.57 μm.Ihe nchọta na-eji ihe nchọta oke oke oke InGaAs/InP.Nzaghachi n'ogo kachasị elu nke 1.55 μm bụ otu usoro ịdị elu dị elu karịa nzaghachi nke ihe nchọpụta silicon avalanche na laser 1.06 μm, na ike kacha nta achọpụta bụ otu usoro nke ịdị ala.Na mgbakwunye, attenuation ikuku nke 1.54μm na 1.57μm lasers dịkwa obere karịa nke lasers 1.06μm.Ya mere, onye na-ahụ maka anya na-echekwa laser nke nwere ike iku ume laser nke naanị ole na ole ruo iri millijoules nwere oke oke nke 10 ruo 20 kilomita.

N'ime afọ ndị na-adịbeghị anya, site na mmepe ngwa ngwa nke erbium-doped fiber laser na teknụzụ laser erbium na ntozu oke nke usoro a, agbakwunyere site na teknụzụ nhazi mgbaama multi-pulse, oriri nke laser fiber miniature na erbium glass lasers nwere obere olu, ịdị mma na ike ga-eji nwayọọ nwayọọ dochie ya Dabere na laser steeti siri ike nwere nnukwu olu, ịdị elu dị elu na ike dị elu dabere na oscillator oscillator optical parametric, ọ ghọwo ebe kachasị mma laser maka ndị na-achọpụta ihe na-ahụ maka laser anya.

SENSUP's LRF-1550-MR/MR anya-safe rangefinder, ọ bụ ezie na 1.55 μm fiber laser pulse peak ike bụ naanị 1,000 kW, ọ na-eji usoro nha anya nke ọtụtụ-pulse (ụkpụrụ iri).Oke nha nha nke ebumnuche ọkọlọtọ 2.3 m × 2.3 m ruru 15 km@5 Hz, oriri ike bụ naanị 7 W, oke ya bụ 840 g.Ọgụgụ 1 bụ foto nke LRF-1550-MR/MR anya na-echekwa anya laser rangefinder
