Abstract: A dyeing device dyes a resin body by vaporizing and depositing a sublimation dye adhered to a dyeing base to a resin body and fixing the dye to the resin body. The dyeing device lowers the pressure inside a closed chamber that closes the periphery of the resin body by a pump. In the state where the adhesion surface of the dyeing base to which the dye is adhered faces the resin body without contact, by heating the dye adhered to the dyeing base inside the closed chamber of which the pressure is lowered, the dye is sublimated, vaporized, and deposited on the resin body. The pressure inside the closed chamber is raised higher than the pressure at the vaporizing and depositing time. By irradiating the resin body on which the dye is vaporized and deposited with electromagnetic wave, the resin body is heated and the dye is and fixed.

Abstract: A laser apparatus has a laser device, a first reflection mirror, an output mirror and a second reflection mirror. The laser device oscillates first and second laser light beams. The first reflection mirror reflects a first laser light beam and is fixed at one end of an optical axis. The second reflection mirror reflects a second laser light beam and is arranged between the laser device and the first reflection mirror so as to be movable with respect to the optical axis. The output mirror reflects the first and second laser light beams and is fixed at the other end of the optical axis.

Consequently, the first laser light beam is amplified between the first reflection mirror and the output mirror. On the other hand, the second reflection mirror is placed on the optical axis in the second position.
