Qhov tseem ceeb tshaj plaws optical tivthaiv nyob rau hauv lub beam shaping systems nyob rau hauv high-power diode lasers yog lub Fast-Axis Collimation optic. Cov lo ntsiab muag yog tsim los ntawm cov iav zoo thiab muaj qhov chaw acylindrical. Lawv cov lej aperture siab tso cai rau tag nrho cov diode tso zis kom sib xyaw nrog cov kab teeb pom kev zoo. Lub siab kis tau tus mob thiab zoo heev collimation yam ntxwv lav lub siab tshaj plaws ntawm beam shaping efficiency raudiode lasers.
Fast Axis Collimators yog compact, kev ua haujlwm siab aspheric cylindrical lo ntsiab muag tsim los rau beam shaping lossis laser diode collimation daim ntaub ntawv. Cov qauv aspheric cylindrical thiab cov lej siab apertures tso cai rau kev sib tsoo ntawm tag nrho cov zis ntawm lub laser diode thaum tswj cov kab teeb pom kev zoo.

Laser Diode Collimation
Laser diodes feem ntau muaj cov yam ntxwv tso zis uas txawv ntawm ntau lwm hom laser. Tshwj xeeb, lawv tsim cov khoom sib txawv heev ntau dua li cov kab sib tsoo. Tsis tas li ntawd, qhov kev sib txawv no yog asymmetrical; lub divergence yog ntau loj nyob rau hauv lub dav hlau perpendicular mus rau lub active khaubncaws sab nraud povtseg nyob rau hauv lub diode nti, piv rau lub dav hlau mus txog rau thaum uas tig mus rau cov txheej. Lub dav hlau divergent ntau yog hu ua "ceev axis", thaum lub divergence qis dua yog hu ua "slow axis".
Siv tau zoo siv laser diode tso zis yuav luag txhua zaus yuav tsum muaj kev sib tsoo lossis lwm yam kev hloov kho ntawm qhov sib txawv no, asymmetric nqaj. Thiab, qhov no feem ntau yog ua los ntawm kev sib cais optics rau qhov ceev thiab qeeb axes vim lawv cov khoom sib txawv. Ua kom tiav qhov no hauv kev xyaum yog li ntawd yuav tsum tau siv optics uas muaj hwj chim nyob rau hauv tsuas yog ib qhov ntev (xws li cylindrical los yog acircular cylindric lo ntsiab muag).
