ーザ光を発振できる装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a solid-state laser oscillation device, and particularly to a device that can oscillate laser light with high efficiency.

〔発明の技術的背景とその問題点〕[Technical background of the invention and its problems]

ーザ装置の場合、発振効率は１チ程度である。このとき
のエネルギ損失には、種々の原因があるが励起ラングの
光を発振媒体が十分に吸収できないことも原因の一つで
ある。In a laser oscillator, the oscillation efficiency of laser light is approximately 10% or less, although it varies depending on the oscillation medium. In particular, in the case of a YAG solid-state laser device widely used for processing such as welding and cutting, the oscillation efficiency is about 1 inch. There are various causes for the energy loss at this time, but one of the causes is that the oscillation medium cannot sufficiently absorb the light from the excitation rung.

ッド方向へ県中して光が照射するようにしている。これ
によってＹＡＧロッドは励起ランプからの光をある程度
無駄なく吸収することができる。In a homogeneous laser oscillator such as YAG, an elliptical cylindrical body consisting of a reflecting mirror is provided around the YAG rod as the oscillation medium and an excitation lamp, and the light from the excitation lamp is irradiated in the opposite direction to the YAG rod. The light is also reflected by a reflector so that it irradiates all over the area in the direction of the YAG rod. This allows the YAG rod to absorb light from the excitation lamp without wasting it to some extent.

域はおよそ７００〜９００ｎｍである。Generally, the laser rod serving as the oscillation medium for a YAG laser uses YAG doped with neodymium ions. The wavelength range of light absorbed by this laser rod for excitation is approximately 700 to 900 nm.

When exciting the laser rod, the YAG laser rod
700 to 900 of the light emitted by the e-flash lamp
Since only nanometer wavelengths are absorbed, light in other wavelength ranges is wasted. Furthermore, this light is not only wasted, but also causes an adverse effect such as inducing a thermal effect on the laser rod itself.

The excitation lamp (3) is turned on by a lighting device (not shown) in order to excite it. At this time, the growth of the light emitted by the excitation lamp (3) is in the range of 200 to 1200 nm, as shown in FIG. Such light is directly transmitted through a cylindrical mirror (
