Qee cov lus nug tseem ceeb txog Erbium Glass Laser

1. Qhov txawv ntawm pulse width (ns) thiab mem tes dav (ms) yog dab tsi?

Qhov txawv ntawm pulse dav (ns) thiab mem tes dav (ms) yog raws li nram no: ns yog hais txog lub sij hawm ntawm lub teeb mem tes, ms yog hais txog lub sij hawm ntawm cov hluav taws xob mem tes thaum lub hwj chim mov.

2. Puas yog tus neeg tsav tsheb laser yuav tsum tau muab lub cim luv luv ntawm 3-6ns, lossis lub module puas tuaj yeem tuav nws tus kheej?

Tsis tas yuav tsum muaj kev hloov kho sab nraud; tsuav yog muaj mem tes nyob rau hauv ms ntau, lub module tuaj yeem tsim ib qho ns lub teeb mem tes ntawm nws tus kheej.

3. Nws puas tuaj yeem txuas ntxiv qhov kev ua haujlwm kub mus txog 85 ° C?

Qhov ntsuas kub tsis tuaj yeem ncav cuag 85 ° C; Qhov kub siab tshaj plaws uas peb tau sim yog -40 ° C txog 70 ° C.

4. Puas muaj kab noj hniav tom qab lub lens uas muaj nitrogen los yog lwm yam khoom los xyuas kom meej tias pos huab tsis tsim sab hauv ntawm qhov kub thiab txias?

Lub kaw lus yog tsim los rau kev siv ntawm qhov kub thiab txias li -40 ° C thiab siab dua, thiab lub teeb ci ntsa iab, uas ua raws li lub qhov rais kho qhov muag, yuav tsis pos huab. Cov kab noj hniav yog kaw, thiab peb cov khoom yog nitrogen-filled qab lub lens, xyuas kom lub lens nyob rau hauv ib tug inert gas ib puag ncig, ua kom lub laser nyob rau hauv ib tug huv qhov chaw.

5. Dab tsi yog qhov nruab nrab lasing?

Peb siv Er-Yb iav ua qhov nruab nrab nquag.

6. Yuav ua li cas yog lub lasing nruab nrab pumped?

Ib tug compact chirp ntawm submount packed diode laser yog uesd longitudinally twj tso kua mis nruab nrab active.

7. Lub laser kab noj hniav ua li cas?

Lub laser kab noj hniav yog tsim los ntawm ib tug coated Er-Yb iav thiab ib tug tso zis coupler.

8. Koj ua tiav li cas 0.5 mrad divergency? Koj puas tuaj yeem ua me dua?

Kev sib xyaw beam-expansion thiab collimation system nyob rau hauv lub laser ntaus ntawv muaj peev xwm ntawm constricting lub divergency kaum sab xis ntawm lub beam kom tsawg li 0.5-0.6mrad.

9. Peb qhov kev txhawj xeeb tseem ceeb cuam tshuam txog lub sijhawm nce thiab poob, muab lub sijhawm luv luv laser. Cov lus qhia tshwj xeeb qhia qhov yuav tsum tau muaj ntawm 2V / 7A. Puas yog qhov no txhais tau hais tias cov khoom siv hluav taws xob yuav tsum xa cov txiaj ntsig no tsis pub dhau 3-6ns, lossis muaj lub twj tso kua mis them ua ke hauv lub module?

Lub 3-6n piav qhia txog lub sijhawm mem tes ntawm lub laser tso zis beam ntau dua li lub sijhawm ntawm lub zog sab nraud. Sab nraud fais fab mov tsuas yog yuav tsum tau lav:

① Cov tswv yim ntawm square yoj teeb liab;

② Lub sijhawm ntawm lub teeb liab yoj square yog nyob rau hauv milliseconds.

10. Dab tsi yog qhov cuam tshuam rau lub zog ruaj khov?

Lub zog ruaj khov yog hais txog lub peev xwm ntawm lub laser kom tswj tau cov khoom siv hluav taws xob zoo ib yam nyob rau lub sijhawm ua haujlwm ntev. Cov yam cuam tshuam rau lub zog ruaj khov muaj xws li:

① Kub variations

② Kev hloov pauv ntawm lub zog laser

③ Kev laus thiab kev kis kab mob ntawm cov khoom siv kho qhov muag

④ Kev ruaj ntseg ntawm lub twj tso kua mis

11. TIA yog dab tsi?

TIA sawv cev rau "Transimpedance Amplifier," uas yog lub suab nrov uas hloov cov teeb liab tam sim no mus rau cov teeb liab voltage. TIA feem ntau yog siv los ua kom pom cov cim tsis muaj zog tam sim no tsim los ntawm photodiodes rau kev ua thiab kev tshuaj xyuas ntxiv. Nyob rau hauv lub tshuab laser, nws feem ntau yog siv ua ke nrog lub tswv yim diode kom stabilize lub laser tso zis zog.
