Abstract

En Øyesikker laser (10) sender med et enkelt resonatorhulrom (16) for både pumpelaseren og den optisk parametriske oscillatoren (22). En Nd:YAG-stav (24) gir forsterkning for lys ved en første bølgelengde. En kombinert Q-svitsj/Brewster-plate (26) Q-svitsjer lyset for å øke dets intensitet og polariserer lyset slik at dets polarisasjonsplan er vinkelrett på Z-aksen til et KTP-krystall som fungerer som den optisk parametriske oscillatoren, hvorved type II fasetilpasningstilstand er tilveiebrakt. Den optisk parametriske oscillatoren omformer lyset ved den første bølgelengden til lys ved en andre bølgelengde som blir utmatet gjennom en delvis reflekterende utkobler ved en bølgelengde som ikke vil skade øynene.
