The laser resonator may comprise a HR end mirror (101), a Q-switch (108), a Nd:YAG laser gain medium (105), a mirror (103) being transmissive at the laser fundamental and reflective at its second-harmonic, a second-harmonic generating non-linear crystal (106), the first optical element (104) being a mirror reflective at the third-harmonic and transmissive at the fundamental and the SH, a non-linear crystal (107) for generating the third-harmonic and a mirror (102) reflecting laser fundamental and SH and transmitting the third-harmonic. The module (150) may be translated to provide a non-damage part of the facet of the third-harmonic generating crystal (107) or replaced in case this non-linear-crystal can not be used any more to extend the lifetime of the laser.

摘要： The present embodiment provides a system and method for lowering the saturated gain level of a thin-disk laser oscillator by multipassing each gain generator in such a way to cancel some of the wavefront error contributions from the disk surfaces. Wavefront aberrations introduced on one pass of the gain disk are canceled through symmetry (140) on successive passes (110,120). The reduced wavefront error significantly improves design space for single-mode resonators. Maximum effectiveness is achieved by rotating the gain disk so that the fold plane-of-symmetry reverses the largest wavefront error or specifically chosen functional forms.

摘要： The present invention provides an optical amplifying device which can be easily downsized, increased in output, and stabilized. An optical amplifying device 1A includes an optical amplifier 10A and an energy supplier 30. The optical amplifier 10A includes an optical amplifying medium 11 and a transparent medium 12. The energy supplier 30 supplies excitation energy (for example, excitation light) to the optical amplifying medium 11. The optical amplifying medium 11 is supplied with the excitation light to amplify light and output it. To-be-amplified light passes through the transparent medium 12 in the optical amplifying medium 11 a plurality of times. The transparent medium 12 can propagate the to-be-amplified light, for example, zigzag inside.

摘要： The present invention relates to a solid-state laser module, and so on, having a structure for enabling optical output of high quality to be obtained. The solid-state laser module includes a vacuum container with windows, and a heat sink, a solid-state laser medium, and a pair of transparent members are housed in the vacuum container in an integrally assembled state. The solid-state laser medium and the pair of transparent members respectively have disk shapes, and the pair of transparent members sandwich the solid-state laser medium. The thermal conductivity of each of the pair of transparent members is higher than the thermal conductivity of the solid-state laser medium. The heat sink has a shape that simultaneously clamps portions of the pair of transparent members that sandwich the solid-state laser medium in between, and a heat insulating region, with a thermal conductivity that is lower than the thermal conductivity of the solid-state laser medium, is provided between the heat sink and the solid-state laser medium.
