Mtundu watsopano wa laser yothamanga ya nanosecond

Rofealaser yozungulira ya nanosecond(gwero la kuwala loyendetsedwa ndi pulse) limagwiritsa ntchito dera lapadera la short-pulse drive kuti likwaniritse kutulutsa kwa pulse kopapatiza ngati 5ns. Nthawi yomweyo, limagwiritsa ntchito ma circuit a laser okhazikika kwambiri komanso ma APC (Automatic Power Control) ndi ATC (Automatic Temperature Control) apadera, zomwe zimapangitsa mphamvu yotulutsa ndi kutalika kwa nthawi kukhala kokhazikika kwambiri. Ndipo imatha kuyang'anira kutentha, mphamvu ndi zina zambiri za gwero la kuwala nthawi yeniyeni. Mndandanda wa magwero a kuwala kwa pulse awa amagwiritsidwa ntchito makamaka pa magwero a mbewu za MOPA structured fiber lasers, lidar, fiber sensing, ndi passive component test.

Pa njira yoyezera molondola pogwiritsa ntchito laser, nthawi ndi yolondola ndipo kukhazikika ndiye njira yothandiza! Ma laser a ROFEA-PLS nanosecond pulsed (magwero a kuwala kozungulira), kutengera kafukufuku wa zaka zambiri wa Rofea Optoelectronics, achepetsa kukula kwa kugunda kwa mtima mpaka kufika pa nanoseconds 5 - zomwe ndi gawo limodzi mwa magawo miliyoni a kuphethira kwa diso! Kuphulika kulikonse kwa kugunda kwa mtima ndi gawo lakuthwa kwambiri pankhondo ya nthawi.

Komabe, mpikisano weniweni wapakati umapitirira apa! Ili ndi kuphatikiza kwawiri kwa APC (Automatic Power Control) ndi ATC (Automatic Temperature Control) mkati, zomwe zimapangitsa kuti pakhale kulamulira kolondola mkati mwa tsatanetsatane. Mphamvu yotulutsa ndi yokhazikika ngati mwala, ndipo kutalika kwa mafunde kumakhalabe kosasintha monga kale, kutsanzikana kwathunthu ndi kusinthasintha kwa magwiridwe antchito komwe kumachitika chifukwa cha kusinthasintha kwa chilengedwe.

Kuwala kolondola kwa ultrashort pulse ndi chida chanu champhamvu pankhondo yoyesera:

■ Malo abwino kwambiri oti mubzale mbewu za MOPAma laser a ulusi, kulimbikitsa mphamvu yowonjezereka;

■ Ikani mzimu wa kuzindikira kolondola kwambiri mu lidar;

Limbikitsani luso lozindikira ulusi wa kuwala kuti ligwire kusintha kwa chizindikiro chofooka kwambiri;

■ Khalani muyezo wagolide woyesera zinthu zopanda ntchito. Kuwala kolondola, sekondi iliyonse imawerengedwa.

Mndandanda wa Rofea-PLSLaser yoyendetsedwa ndi Ns(gwero la kuwala koyendetsedwa ndi mpweya), lokhala ndi kuthwa kwa ma nanosecond asanu komanso luntha lolamulira kawiri, ndiye mnzanu woyenera kwambiri poyesa molondola ma pulses afupi kwambiri!

Zinthu zomwe zili mu malonda

M'lifupi mwake mwa kugunda kwa mtima kopapatiza kwambiri kumatha kufika pa 5ns

Ma wavelength angapo alipo: 850, 905, 1064, 1310, 1550nml. Kufupika kwa kugunda kwa mtima ndi kuchuluka kwa ma frequency obwerezabwereza kumatha kusinthidwa.

Mawonekedwe olumikizirana a chizindikiro chogwirizana

Imathandizira ntchito yoyambitsa yakunja
