PROBLEM TO BE SOLVED: To obtain a solid laser oscillator whose output can be made high by an arrangement wherein a laser beam which has been incident on a solid laser medium is arranged in such a way that it is reflected by a first reflecting mirror constituting its unit constituent body and the laser beam is radiated from the solid laser medium so as to be incident on a solid laser medium constituting a next unit constituent body. SOLUTION: Pairs of laser crystals 21 and reflecting mirrors 5 which correspond to each other correspond to unit constituent bodies. An excitation state is generated inside every laser crystal 21, a laser oscillation state is realized, and a laser beam is reflected by every reflecting mirror 5 situated at the rear of every laser crystal 21. Then, it is returned by turning a V-shaped optical path, and it traces an optical path connected to the opposite laser crystal 21 at the outside of every laser crystal 21. A total reflecting mirror 6 which totally reflects the laser beam is arranged at one end of the optical path which leaves the laser crystals as a group, and an output mirror 7 which displays a transmission characteristic to a certain degree with reference to the laser beam is arranged at the other end. As a result, a laser beam 8 is taken out from the output mirror 7. |
