Abstract:
(EN) A laser device (1) oscillates a plurality of pulses of output light (200) obtained by amplifying light emitted from a laser medium (26) which emits light by absorbing excitation light (100) and to which ytterbium has been added. A spatial filter (40) for limiting spreading about an optical axis is disposed in either the optical path of the light emitted from the laser medium (26) or the optical path of the output light (200) that has exited an optical resonator (20).
(FR) La présente invention concerne un dispositif laser (1) qui fait osciller une pluralité d’impulsions de lumière de sortie (200) obtenues par amplification de la lumière émise par un milieu laser (26) qui émet de la lumière par absorption d’une lumière d’excitation (100) et auquel de l’ytterbium a été ajouté. Un filtre spatial (40) pour limiter l’étalement autour d’un axe optique est disposé dans le trajet optique de la lumière émise par le milieu laser (26) ou le trajet optique de la lumière de sortie (200) qui est sortie d’un résonateur optique (20).
(JA) 励起光(100)を吸収して光を発するイッテルビウムが添加されたレーザー媒質(26)が発した光を増幅した出力光(200)を、複数のパルス状に発振するレーザー装置(1)では、レーザー媒質(26)が発した光の光路または光共振器(20)から出射後の出力光(200)の光路のいずれかの光路に、光軸周りの広がりを制限する空間フィルター(40)が設けられる。
