Lub luag haujlwm ntawm tus beam shaper yog hloov cov Gaussian profile ntawm lub teeb ci (feem ntau yog laser) mus rau hauv Top-Hat profile.
Tus qauv tsim yog raws li tus qauv transmissive uas siv tau nrog qhov loj tshaj plaws ntawm 4.6 hli thiab qhov tso zis ntawm 8 hli. Lub teeb tso zis tom qab lub beam shaper yog collimated, yog li nws tuaj yeem siv nrog cov lens ib txwm. Peb qhib rau lwm yam kev xav tau wavelength raws li koj cov ntawv thov tshwj xeeb.
