High-power Laser Bars rau Optical Pumping thiab Direct-Diode-Laser (DDL) kev siv hauv cov khoom siv, tshuaj, lossis kev hnov
Brandnew Lasers muab ntau yam kev xaiv tsis ntim cov laser diode. Qee qhov kev xaiv no suav nrog wavelengths xws li 760 nm mus txog 1060 nm, ib leeg-emitter laser diode chips nrog rau 10 W tso zis zog thiab laser diode arrays / laser diode tuav nrog txog 350 W tso zis zog, thiab nruam nthwv dej (CW) thiab quasi-continuous wave (QCW) xaiv.
Peb tsim peb cov khoom siv semiconductor raws li kev tswj hwm nruj tshaj plaws. Peb tsuas yog ua haujlwm nrog lub xeev-of-the-art epitaxy, ua, thiab facet txheej tshuab. Peb cov tuav, semi-bars, thiab ib leeg emitters ua tau raws li qhov xav tau ntau tshaj plaws: Lawv muaj kev ntseeg siab heev, ua haujlwm tau zoo, thiab ruaj khov.
Peb cov khoom semiconductor tau yooj yim sib sau ua ke siv cov txheej txheem soldering. Cov khoom txhawb nqa ob qho tib si muag muag (indium) thiab tawv tawv (kub / tin). Peb xa peb cov laser tuav rau koj nrog cov qauv emitter sib cais ntawm p-sab raws li tus qauv. Raws li kev thov, peb kuj tuaj yeem tsim cov kab txuas nrog txuas ntxiv p-sab metallization thiab hloov kho facet coatings, siv cov AR txheej qis rau kev sib dhos ntawm cov khoom siv sab nraud.
Kev sib raug zoo nrog cov khoom sau peb paub qhov txawv ntawm peb pawg khoom rau peb 10 hli dav tuav, txhua qhov kev txhawb nqa tshwj xeeb thiab kev ua haujlwm tswj hwm:
• Cov khoom ntim qis qis (typ. Tsawg dua lossis sib npaug li 30% cov khoom ua tiav) featuring low beam-parameter-product (BPP) suited for fiber coupling
• High-power bars (typ. 50% filling factor) txog li 300 W cw- thiab hard-pulse (hp) ua hauj lwm haum rau optical pumping thiab direct-diode-laser (DDL) daim ntaub ntawv
• QCW tuav (typ. FF> 65% sau qhov tseem ceeb): rau txog 500 W qcw- thiab ntev-mem tes (lp) ua haujlwm haum rau kev siv kho qhov muag thiab kev siv kho mob
Cov txiaj ntsig:
• Qhov zoo tshaj plaws: Peb nruj me ntsis saib xyuas cov khoom ntawm peb cov khoom semiconductor hauv cov txheej txheem kom meej meej.
• Hwj chim: siab, txhim khu kev qha tso zis zog thiab zoo tagnrho beam yam ntxwv.
• Kev Lag Luam: Peb cov khoom siv hluav taws xob semiconductors muaj txiaj ntsig zoo thiab muaj lub neej ua haujlwm ntev.
