Solid state laser has switch that is moved between two positions, to select either of branch resonators such that laser beams branched at common resonator and passed along branch resonators are incident on dispersion prisms

摘要

#CMT# #/CMT# The solid state laser has common laser resonator (1) that has mirror (2), active medium (3), acousto-optic modulator (4), and switch (5), and branch resonators (6). The branch resonators have dispersion prisms (12,14,15), non-linear crystals (10,11) and resonator mirrors (8,9). The switch is moved between two positions, to select either of branch resonators such that laser beams branched at common resonator and passed along branch resonators are incident on dispersion prisms (12,15) where laser beams pass along same axis. #CMT#USE : #/CMT# Solid state laser. #CMT#ADVANTAGE : #/CMT# Since switch is moved to select either of branch resonators, the laser beams branched at common resonator and passed along the branch resonators are incident on dispersion prisms, reliable deflection of laser beam can be achieved even if the target position of switch is slightly deviated. The structure of solid state laser is made compact and simple, so that the cost of the laser is reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the solid state laser. 1 : Common laser resonator 2 : Mirror 3 : Active medium 4 : Acousto-optic modulator 5 : Switch 6 : Branch resonators 8,9 : Resonator mirrors 10,11 : Non-linear crystals 12,14,15 : Prisms.
