Title: Lasing method and laser device
Inventor: SEKIGUCHI HIROSHI
IPC: H01S3/042
Filed: 1988-06-30
Abstract: PURPOSE:To achieve a uniform temperature distribution by conducting a go-and- back movement of the laser medium with a plurality of return points established in at least one of the two different shuttle motions. CONSTITUTION:The laser medium 1 is made of laser glass. The rightmost area (f) of the laser medium 1 comes to an irradiation position, the laser medium is in one of the two return positions corresponding to two types of shuttle motions of a go-and-back movement and it moves right. When the leftmost area (a) of the laser medium 1 comes to an irradiation position, it starts another shuttle motion and it moves left. When an area (e), which is next to the area (f), comes to an irradiation position, the laser medium 1 starts a shuttle motion again. The laser medium 1 continues to move right and when an area (b), which is adjacent to the leftmost area (a), comes to an irradiation position, the laser medium starts a shuttle motion again. This cycle of movement repeats. Compared with a case that the laser medium always returns at the same points, in this case less heat is accumulated at one place. By this device, therefore, a more uniform temperature distribution of the laser medium is achieved with the output variation reduced.
