Abstract

En faststoffslaser har en plate av lasermateriale (5). Platen (5) er lang- strakt og har et rektangulært tverr- snitt, hvor platen nedre flate (5a) kontakter et plateunderlag (6) som er av et materiale med høy varmeledningsevne. Energi for å drive lasermediet tilveie- bringes av en blitzlampe (8). Øvre og nedre flater (5a, 5b) av platen (5) er polert til en optisk glatt finish, slik at lys er i stand til å forplante seg i en stort sett aksial retning gjennom platen (5). Sideflater (5c, 5d) av platen (5) er polert og deretter gjort ru på nytt for å tilveiebringe en finish med en overflateskadesone som i dybde kan sammenliknes med bølgelengden av laservirkningsemisjonen. For en laser- virkningsbølgelengde på l pm ligger dybden av overflateskade i området l pm.
