Tsis ntev los no, cov pab pawg tshawb fawb ntawm xibfwb Lu Huadong los ntawm kev ua kom muaj kev cuam tshuam rau cov txheej txheem tsim kho tshiab spontaneous radiation in the laser pulse formation process was greatly reduced, effectively narrowing the pulse width of the output laser and reducing the timing jitter of the laser pulse. Finally, a nanosecond pulse 830 nm near-infrared laser output with an output power of 7.75 W and a spectrum width of 400 {. 93 MHz tau txais, thiab cov qauv sib txawv ntawm nws cov mem tes sijhawm Jitter tsuas yog 2.285 ns. Txoj kev kawm no muaj lub tswv yim tshiab rau kev paub txog kev ua kom nruj, muaj zog, qhov siab me me uas tsis muaj xauv tswj.
Nyob ze-infrared teeb lub teeb (700 ~ 1000 nm) tau siv dav hlau ntxiv, thiab lub teeb ib puag ncig zoo nkauj, yog li qhov pom kev zoo, yog li kom tau raws li cov kev xav tau ntawm cov ntawv thov muaj kev ruaj ntseg xws li kev nyab xeeb kom muaj kev ruaj ntseg, laser kev kwv yees thiab Lithography.
Nyob rau tam sim no, nce-hloov cov titanium sapphire lasers feem ntau yog siv kom muaj zog ntawm lub zog, hloov pauv cov khoom siv hluav taws xob zoo siab, tsis muaj peev xwm hloov kho lub zog Sapphire laser tau ua haujlwm ntawm lub zog qis, lub sijhawm tso tawm ntawm cov khoom siv hluav taws xob tsis muaj txiaj ntsig, vim yog qhov kev lees paub ntawm cov theem ntawm cov theem sib txuam txheej txheem, lub spectral dav ntawm cov zis teeb liab lub teeb yog qhov uas tsis tshua nqaim thiab muab tso rau qhov ruaj khov ntawm lub system .
Txhawm rau kom kov yeej cov kev sim tam sim no, cov txheej txheem kev tshawb fawb tau npaj tseg ntawm cov txheej txheem tsim kho qhov muag ua ntej thiab tom qab kev hloov kho ntawm cov txheej txheem ntawm cov txheej txheem tshiab Kev tshuaj xyuas . raws li muaj nyob hauv daim duab 1, nyob rau hauv nruab nrab ntawm lub zog, thiab tom qab ntawd cov khoom siv laser, thiab tom qab ntawd cov khoom siv laser, thiab tom qab ntawd cov khoom siv nyiaj laser, thiab tom qab ntawd cov khoom siv laser, thiab tom qab ntawd cov khoom siv laser, thiab tom qab ntawd cov khoom siv nyiaj laser, thiab tom qab ntawd cov khoom siv nyiaj Laser, thiab tom qab ntawd cov khoom siv laser, thiab tom qab ntawd cov khoom siv laser, thiab tom qab ntawd cov khoom siv nyiaj laser, thiab tom qab ntawd cov khoom siv laser, thiab tom qab ntawd cov khoom siv laser, thiab tom qab ntawd cov khoom siv laser, thiab tom qab ntawd cov kev ua haujlwm ntawm lub zog thiab thaum cov txheej txheem kho qhov muag tau muab qhia rau cov txheej txheem eminetic tsim tawm hauv lub sijhawm ua haujlwm Cov teeb liab teeb liab ntawm cov txheej txheem kho kho qhov muag, cov mem tes sij hawm jitter ntawm cov zis zoo li.
Cov pab pawg tshawb fawb tsim cov txheej txheem ua kom zoo nkauj thiab muaj kev tswj hwm qhov nruab nrab thiab kho qhov tsis muaj txiaj ntsig thiab kho qhov muag tsis muaj zog thiab kho qhov muag tsis muaj zog thiab kho qhov muag tsis muaj zog thiab kho qhov muag tsis muaj zog thiab kho qhov tsis muaj qhov sib thooj thiab kho dua tshiab} Lub teeb liab teeb ntawm cov txheej txheem ntawm cov txheej txheem, ob pawg ntawm nanosecond pulse {}} pulse / mem tes ntxiv, txhawm rau nqaim lub spectrum dav ntawm lub Ti: sapphire laser, etalons nrog thicknesses ntawm 0.}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} kev sib xyaw ua ke nrog cov teeb liab teeb ntawm lub qhov muag Parametric cov txheej txheem.
In the experiment, the pulse timing of the two pump lights is controlled by a delay/pulse generator, and the time domain characteristics of the output laser after the introduction of the optical parametric process are optimized, as shown in Figure 3. After the optical parametric process is introduced into the gain-switched laser, the signal light generated by the optical parametric process greatly reduces the proportion of the spontaneous Emission cov txheej txheem hauv cov txheej txheem kev tsim cov mem tes los txo qis ntawm 66 {{. Nyob rau tib lub sijhawm, vim muaj tus yam ntxwv tsis muaj ncua ntawm lub teeb twj tso kua mis thiab lub teeb liab teeb tsa tau txo los ntawm 9.926 ns rau 2.285 ns.
Tom qab qhia cov txheej txheem kho kho qhov muag hauv qhov nce dua li ntawm ob lub teeb laser tau zoo dua 0, {{{18% (rms), raws li qhia hauv daim duab 4 (a); Cov yam ntxwv ntev hom tau ntsuas tau ntsuas siv qhov kev ntsuas fp cavity (sa} b, thorlabs), raws li qhia hauv Daim Duab 4 (b); Cov yam ntxwv hloov cov yam ntxwv tau ntsuas siv tus nqaj zoo dua Analyzer (M) Nyob rau tib lub sijhawm, los ntawm synchronously scanning lub kaum sab xis ntawm cov crystal lim thiab ntsuas kub ntawm lub rooj zaum kub ntawm lub siab, raws li qhia hauv daim duab 4 (d).
