DPSS Nd: YAG Laser Daim Ntawv Thov hauv Pob Zeb Diamond Txiav
DPSS (Diode-Pumped Solid-State) Nd: YAG (Neodymium-doped Yttrium Aluminium Garnet) laser uas tsim cov zaus-ob npaug 532 nm lub teeb ntsuab ua haujlwm los ntawm cov txheej txheem sophisticated uas muaj ntau yam tseem ceeb thiab lub hauv paus ntsiab lus ntawm lub cev.

Txoj Cai Ua Haujlwm ntawm DPSS Laser
1. Diode Pumping:
Cov txheej txheem pib nrog lub laser diode, uas emits infrared teeb. Lub teeb no yog siv los "twj" lub Nd:YAG siv lead ua, lub ntsiab lus nws ua rau cov neodymium ions kos rau hauv yttrium aluminium garnet crystal lattice. Lub laser diode yog tuned rau lub wavelength uas phim qhov nqus spectrum ntawm Nd ions, kom ntseeg tau tias muaj zog hloov pauv.
2. Nd:YAG Crystal:
Nd:YAG siv lead ua yog qhov nruab nrab nce siab. Thaum cov neodymium ions zoo siab los ntawm lub teeb ci, lawv nqus lub zog thiab txav mus rau lub zog siab dua. Tom qab lub sijhawm luv luv, cov ions hloov pauv rov qab mus rau lub xeev qis zog, tso lawv lub zog khaws cia hauv daim ntawv ntawm photons. Cov txheej txheem no hu ua spontaneous emission.

3. Pej Xeem Inversion thiab Stimulated Emission:
Rau kev txiav txim laser tshwm sim, cov pej xeem inversion yuav tsum tau ua tiav, qhov ntau ions nyob rau hauv lub xeev zoo siab tshaj nyob rau hauv qis zog lub xeev. Raws li photons thaws rov qab thiab tawm ntawm daim iav ntawm lub laser kab noj hniav, lawv ua rau lub siab Nd ions tso tawm ntau photons ntawm tib theem, kev taw qhia, thiab wavelength. Cov txheej txheem no hu ua stimulated emission, thiab nws amplifies lub teeb siv nyob rau hauv lub siv lead ua.
4. Laser Cavity:
Lub laser kab noj hniav feem ntau muaj ob daim iav ntawm qhov kawg ntawm Nd:YAG siv lead ua. Ib daim iav muaj qhov cuam tshuam zoo heev, thiab lwm qhov yog ib feem ntawm qhov cuam tshuam, tso cai rau qee lub teeb kom dim raws li cov zis laser. Cov kab noj hniav resonates nrog lub teeb, amplifying nws los ntawm rov qab rounds ntawm stimulated emission.
5. Zaus Doubling (Second Harmonic Generation):
Txhawm rau hloov lub teeb zaus zaus (feem ntau yog 1064 nm emitted los ntawm Nd:YAG) mus rau lub teeb ntsuab (532 nm), ib zaus-doubling siv lead ua (xws li KTP - Potassium Titanyl Phosphate) muab tso rau hauv lub laser txoj kev. Cov siv lead ua no muaj cov cuab yeej uas tsis yog-linear optical uas tso cai rau nws coj ob lub photons ntawm thawj lub teeb infrared thiab muab tso rau hauv ib qho photon nrog ob zaug lub zog, thiab yog li ntawd, ib nrab ntawm lub wavelength ntawm thawj lub teeb. Cov txheej txheem no hu ua thib ob harmonic tiam (SHG).
6. Tso zis ntawm lub teeb ntsuab:
Qhov tshwm sim ntawm qhov zaus ob npaug yog qhov emission ntawm lub teeb ntsuab ntawm 532 nm. Lub teeb ntsuab no tuaj yeem siv rau ntau yam kev siv, suav nrog laser pointers, laser qhia, fluorescence excitation hauv microscopy, thiab cov txheej txheem kho mob.
Cov txheej txheem tag nrho no yog qhov ua tau zoo thiab tso cai rau kev tsim cov khoom siv hluav taws xob siab, coherent ntsuab teeb nyob rau hauv ib qho kev cog lus thiab txhim khu kev qha. Tus yuam sij rau DPSS laser txoj kev vam meej yog kev sib xyaw ua ke ntawm cov khoom lag luam hauv lub xeev tau txais xov xwm (Nd:YAG siv lead ua), siv tau zoo diode, thiab muaj txiaj ntsig zoo dua ob npaug kom ua tiav qhov xav tau ntawm lub teeb.
