Dab tsi yog Ultrafast Lasers thiab Yuav Siv Li Cas?

Txhais ntawm Ultrafast Lasers

Ultrafast lasers xa mus rau lasers uas emit luv luv pulses, feem ntau nyob rau hauv lub picosecond (10⁻¹² vib nas this) los yog femtosecond (10⁻¹⁵ vib nas this). Vim lawv lub sijhawm luv luv luv, cov lasers no cuam tshuam nrog cov ntaub ntawv feem ntau los ntawm cov teebmeem uas tsis yog thermal, nonlinear, txo cov cua kub thiab thermal puas. Cov yam ntxwv tshwj xeeb no ua rau ultrafast lasers zoo tagnrho rau precision micromachining, cov txheej txheem kho mob, thiab kev tshawb fawb tshawb fawb.

Kev siv ntawm Ultrafast Lasers

Nrog rau lawv lub siab ncov lub zog thiab qhov cuam tshuam thermal tsawg, ultrafast lasers tau dav siv thoob plaws ntau yam lag luam, suav nrog:

1. Muaj Micromachining: Ultrafast lasers pab kom meej txiav, drilling, kos npe, thiab ua tiav ntawm cov qib micro thiab nano nrog cov cheeb tsam uas muaj cua sov tsawg.

2. Kev Kho Mob thiab Biomedical Imaging: Hauv ophthalmology, femtosecond lasers yog siv rau kev phais qhov muag LASIK, muab cov pob txha txiav kom meej nrog cov teeb meem tom qab phais me me. Tsis tas li ntawd, lawv tau siv rau hauv multiphoton microscopy thiab biomedical cov ntaub so ntswg tsom.

3. Kev Tshawb Fawb Txog Kev Tshawb Fawb: Cov lasers no ua lub luag haujlwm tseem ceeb hauv lub sij hawm daws teeb meem spectroscopy, nonlinear optics, quantum tswj, thiab kev tshawb fawb cov ntaub ntawv tshiab, tso cai rau cov kws tshawb fawb los tshawb txog ultrafast dynamics ntawm qib atomic thiab molecular.

4. Kev sib txuas lus kho qhov muag: Qee lub lasers ultrafast, xws li 1.5μm fiber ntau lasers, ua haujlwm hauv qhov tsis tshua muaj kev sib txuas lus fiber ntau, ua haujlwm ruaj khov rau cov ntaub ntawv xa mus ceev.

Fais fab thiab Performance Parameters

Ultrafast lasers yog tus cwj pwm los ntawm ob lub zog tseem ceeb:

1. Lub zog nruab nrab: Ntau yam ntawm kaum tawm milliwatts mus rau ob peb watts lossis siab dua, nyob ntawm cov ntawv thov.

2. Peak zog: Vim lub sijhawm luv luv luv, lub zog siab tuaj yeem ncav cuag ob peb kilowatts mus txog ntau pua kilowatts. Piv txwv li, qee qhov femtosecond lasers tuav lub zog nruab nrab ntawm 1W, thaum lawv lub zog siab tshaj plaws yog ntau qhov kev txiav txim siab dua.

Lwm qhov tseem ceeb ntawm kev ua tau zoo suav nrog pulse repetition rate, mem tes zog, thiab mem tes dav, txhua yam yuav tsum tau ua kom zoo raws li cov kev xav tau ntawm kev lag luam thiab kev tshawb fawb.

Ua Lag Luam Ua Lag Luam thiab Kev Txhim Kho Kev Lag Luam

Ntau lub tuam txhab lag luam thoob ntiaj teb tswj hwm kev lag luam ultrafast laser:

1. Coherent, Spectra-Physics, Newport (MKS) - Tsim cov tuam txhab nrog cov cuab yeej paub tab thiab ntau yam kev lag luam thiab kev tshawb fawb.

2. TRUMPF, IPG Photonics - Cov thawj coj lag luam hauv kev lag luam laser kev daws teeb meem.

3. Tuam Tshoj Manufacturers (Han's Laser, GaussLasers, YSL Photonics) - Cov neeg ua si tawm tshiab ua rau muaj kev nce qib tseem ceeb hauv kev teeb tsa laser, hom kev ntsuas cov thev naus laus zis, thiab kev sib koom ua ke.

Cooling Systems thiab Thermal Management

Txawm hais tias lawv lub zog nruab nrab qis, ultrafast lasers tsim cov cua sov tam sim ntawd vim lawv lub zog siab. Cov tshuab ua kom txias tau zoo yog qhov tseem ceeb los xyuas kom muaj kev ua haujlwm ruaj khov thiab ua haujlwm ntev.

Chiller Systems: Ultrafast lasers feem ntau nruab nrog cov tshuab chillers nrog kev tswj qhov kub thiab txias ntawm ± 0.1 ° C lossis zoo dua los tswj kev ua haujlwm ruaj khov laser.

TEYU CWUP-series Chillers : Tsim tshwj xeeb rau ultrafast laser txias, cov laser chillers muaj PID-tswj kub tswj nrog precision siab li 0.08 ° C txog 0.1 ° C. Lawv kuj txhawb RS485 kev sib txuas lus rau cov chaw taws teeb saib xyuas thiab tswj, ua rau lawv zoo tagnrho rau 3W -60W ultrafast laser systems.

Yav tom ntej Trends nyob rau hauv Ultrafast Lasers

Ultrafast laser kev lag luam yog evolved mus rau:

1. Shorter Pulses, Siab Peak Power: Kev nce qib tsis tu ncua hauv hom-xauv thiab pulse compression yuav ua rau attosecond mem tes lasers rau cov ntawv thov tshwj xeeb.

2. Modular thiab Compact Systems: Yav tom ntej ultrafast lasers yuav muaj kev sib koom ua ke ntau dua thiab cov neeg siv khoom zoo, txo qhov nyuaj thiab cov nqi siv.

3. Tus nqi qis thiab Localization: Raws li cov khoom tseem ceeb xws li laser muaju, cov twj tso kua mis, thiab cov tshuab ua kom txias ua rau hauv tsev, cov nqi laser ultrafast yuav poob qis, ua rau kev siv dav dav.

4. Kev sib koom ua ke hla kev lag luam: Ultrafast lasers yuav nce sib koom ua ke nrog cov teb xws li kev sib txuas lus kho qhov muag, cov ntaub ntawv quantum, precision machining, thiab biomedical research, tsav tsheb tshiab technologies.
