Definitions
- the present invention relates to a Q switch structure and a method for manufacturing a Q switch structure.
- a laser device equipped with a Q switch
- a laser device in which a first resonant mirror, a solid-state laser material, a Q switch, and a second resonant mirror are arranged in that order is known. That is, a laser device is known in which a solid-state laser material and a Q switch are arranged between a pair of resonant mirrors composed of a first resonant mirror and a second resonant mirror.
- Non-Patent Document 1 discloses a compact laser device in which a solid-state laser material and a Q switch are arranged between a pair of resonant mirrors.
- the Q switch is a passive Q switch that utilizes saturability, The Q-switch cannot be actively controlled.
- Non-Patent Document 2 discloses a technique for actively controlling the Q switch using the electro-optic effect. Therefore, the Q switch is an obstacle to miniaturization of the laser device.
- Non-Patent Document 3 discloses a technique for actively controlling the Q switch using the acousto-optic effect, but the thickness of the Q switch is 32 mm, and the Q switch is an obstacle to miniaturization of the laser device. ing.
- Patent Document 1 a solid-state laser material and a Q switch are arranged between a pair of resonant mirrors as a technique for activating the Q switch under the constraint that it does not hinder the miniaturization of the laser device.
- Patent Document 1 describes a Q switch using a magneto-optical (MO) mechanism as described above. From the viewpoint of downsizing the laser device, it is desirable that the space between the solid-state laser medium and the magneto-optical mechanism is as small as possible.
- FIG. 13 of Patent Document 1 a configuration is proposed in which a solid-state laser medium and a magneto-optical film or the like are integrated. However, no specific integration method has been proposed.
- the present invention has been made in view of the above problems, and an object of the present invention is to provide a Q-switch that contributes to the miniaturization of laser devices and that can handle high optical output.
- the present invention provides a Q-switch structure comprising a solid-state laser medium and a magneto-optical material, wherein the solid-state laser medium and the magneto-optical material are joined and integrated, wherein the solid-state laser A Q-switch structure is provided, wherein the thickness of the medium is 1 mm or more, and the solid-state laser medium and the magneto-optical material are directly bonded.
- the solid-state laser medium and the magneto-optical material are joined and integrated, so a small Q switch structure can be obtained.
- the solid-state laser medium and the magneto-optical material are directly bonded, there is no reduction in performance due to deterioration of the intervening material, unlike the case where a material is interposed between them.
