MOPA (Master Oscillator Fais Fab Amplifier) yog lub laser architecture uas txhim kho cov txiaj ntsig kev ua tau zoo los ntawm kev sib cais cov noob (tus tswv oscillator) los ntawm lub zog amplification theem. Lub tswv yim tseem ceeb yog tsim kom muaj cov txiaj ntsig zoo ntawm cov noob mem tes nrog tus tswv oscillator (MO), uas yog tom qab ntawd lub zog-amplified los ntawm lub hwj chim amplifier (PA), thaum kawg xa high-power, high-beam-zoo, thiab parameter-controlled laser pulses. Cov qauv no tau siv dav hauv kev lag luam, kev tshawb fawb tshawb fawb, thiab kev siv kho mob.
1.Qhov tseem ceeb ntawm MOPA Amplification
①Flexible thiab Controllable Parameters:
- Kho tau yooj yim Pulse Width:
Cov mem tes dav ntawm cov noob mem tes tuaj yeem hloov kho ntawm nws tus kheej ntawm theem amplifier, feem ntau yog li ntawm 1 ns txog 200 ns.
- Adjustable Repetition Rate:
Txhawb ntau hom mem tes repetition tus nqi, los ntawm ib zaug txhaj rau MHz-theem high-frequency pulses, kom ua tau raws li kev xav tau ntau yam (xws li, high-speed marking thiab sib sib zog nqus engraving).
②High Beam Quality:
Cov yam ntxwv tsis tshua muaj suab nrov ntawm cov noob yog khaws cia tom qab kev nthuav dav, xa qhov ze-diffraction-limited beam zoo (M² < 1.3), haum rau precision machining.
③High Pulse Zog thiab Stability:
Nrog rau ntau theem amplification, ib leeg-pulse zog tuaj yeem ncav cuag qib millijoule nrog tsawg zog hloov pauv (<1%), zoo tagnrho rau cov ntawv thov kev lag luam siab.
④Cold Processing Peev Xwm:
Nrog luv pulse widths (piv txwv li, nyob rau hauv lub nanosecond range), thermal teebmeem ntawm cov ntaub ntawv tuaj yeem txo qis, ua rau kev ua haujlwm zoo ntawm cov khoom siv tawv tawv xws li iav thiab ceramics.
2. Master Oscillator (MO):
Lub MO generates tsawg-power tab sis precisely tswj noob pulses. Cov noob qoob loo feem ntau yog semiconductor laser (LD) lossis fiber ntau laser, ua cov pulses ntawm kev ncaj qha lossis sab nraud.
3.Fais fab Amplifier (PA):
Lub PA siv fiber ntau amplifiers (xws li ytterbium-doped fiber ntau, YDF) los ua kom cov noob pulses nyob rau ntau theem, txhawb zog mem tes thiab nruab nrab lub zog. Amplifier tsim yuav tsum zam cov teebmeem tsis zoo xws li txhawb nqa Brillouin scattering (SBS) thiab txhawb nqa Raman tawg (SRS), thaum tuav cov nqaj zoo.
