Title (EN) LASER APPARATUS AND EXTREME-ULTRAVIOLET LIGHT GENERATION SYSTEM USING THE SAME
(FR) APPAREIL LASER ET APPAREIL GÉNÉRATEUR DE LUMIÈRE ULTRAVIOLETTE EXTRÊME
Abstract: front page image
(EN)A MOPA laser apparatus 3 including a master oscillator 110 configured to output a pulsed laser beam, at least one amplifier 130i provided on the path of the pulsed laser beam output from the master oscillator, and at least one first optical beam shutter 120i (also called here isolator) provided on the path of the pulsed laser beam, said first optical beam shutter (also called here isolator) including two polarisation splitters and a Pockels cell located in- between including an electro-optical crystal being one of a GaAs crystal and a CdTe crystal.
(FR)L'invention concerne un appareil laser qui peut comprendre un oscillateur maître servant à produire un faisceau laser à impulsion, au moins un amplificateur installé sur une trajectoire du faisceau laser à impulsion venant de l'oscillateur maître et au moins un premier isolateur optique placé sur la trajectoire du faisceau laser à impulsion, le premier isolateur optique comprenant au moins un cristal GaAs et un cristal CdTe comme cristal électro-optique.
