Lub hauv paus ntsiab lus thiab kev thov ntawm cov zog siab nws-ne laser

Nws-ne laseryog ib qho ntawm cov roj ua ntej kom ua tiav cov zis txuas ntxiv. Nws tsim tawm ruaj khov liab laser ntawm lub wavelength ntawm 632.8 nanometers los ntawm kev tawm tsam ntawm kev sib zog ntawm helium (nws) thiab neon (non) gases.

Thaum ntxov Helium-Nason lasers muaj lub zog ntawm tsuas yog milliwatts, tab sis nrog kev pom zoo, thiab tau dhau los ua lub teeb pom kev zoo rau kev tshawb fawb thiab kev ntsuas kev lag luam. Nrog cov thev naus laus zis, muaj ntau lub zog helium-neon rasers tau pom, thiab tau nthuav dav rau kev siv rau hauv precision, cuam tshuam, thiab lwm daim teb. Nws yog tseem yog ib qho ntawm cov neeg sawv cev classic ntawm cov roj av.

High-zog Helium-Neon lasers (nws yog lasers) muaj tus nqi tshawb nrhiav, thiab kev kho mob vim lawv qhov kev ruaj khov, thiab lub neej ntev. Piv nrog rau lwm cov lasers, xws li co₂ lasers (muaj zog beams (ua kom muaj kev ntsuas me me Tsis tas li ntawd, lawv muaj tus qauv yooj yim, cov nqi kho tus nqi qis, thiab tsis tas yuav ua rau cov haujlwm ua kom txias, ua rau lawv haum rau kev ua haujlwm ntev ruaj khov. Txawm hais tias nws nyuaj rau kev sib tw nrog cov khoom siv khov kho los yog Helium-Neon Lasers tseem muaj cov ntaub ntawv tsis muaj zog uas xav tau cov nqaj siab zoo.

Kev sib piv nrog lwm cov lasers

Lub hauv paus ntsiab lus ntawm High-zog nws-ne laser
1. Ua Haujlwm Nruab Nrab:
Ib cov roj sib xyaw ntawm helium (nws) thiab helium (ne) (tib si piv 5: 1 ~ 10: 1) yog siv thiab kaw hauv lub khob lossis quartz tso cov raj.
