Abstract

Išradimas susijęs su tolygiai derinamais siauros spektrinės juostos lazeriniais šaltiniais. Matomosios ir artimosios infraraudonosios srities spektroskopijai skirtas šaltinis yra sudarytas iš kaupinimo impulsų šaltinio, suformuojančio didelio impulsų pasikartojimo dažnio pikosekundinių impulsų paketus, ir sinchroniškai kaupinamo parametrinio šviesos osciliatoriaus. Kaupinimo šaltinis apima kietakūnį regeneracinį stiprintuvą, kurio rezonatoriaus viduje yra vienas arba du elektro-optiniai raktai. Raktai laiko intervalui, ilgesniam negu rezonatoriaus apėjimo laikas, sukuria dalinį rezonatoriaus pralaidumą, ir išmeta dalį viduje cirkuliuojančio impulso energijos. Suformuojami (5-10) ns trukmės impulsų paketai su pikosekundinių didelės smailinės galios impulsų užpilda. GHz eilės kaupinimo impulsų pasikartojimo dažnis leidžia konstruoti kompaktišką parametrinį šviesos osciliatorių. Visas parametrų rinkinys užtikrina aukštą energinį efektyvumą, stabilumą ir galimybę tiekti iki 10kHz paketų pasikartojimo dažnio išėjimo impulsų paketus. Kaupinant artimojo infraraudonojo diapazono lazerio spinduliuote arba jo harmonikų spinduliuote, bangos ilgio derinimo diapazonas perdengia matomąją ir artimąją infraraudonąją spektro sritį.
