Description

Technical Field [0001] The present invention relates to a mount assembly for an optical element,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mount assembly for adjusting an optical element position, and more particularly, to a mount assembly for adjusting an optical element position.

The laser device is a device for oscillating a laser beam having monochromatic, coherence, and collimation, which are three characteristics different from those of ordinary natural light or light emitted from a lamp.

The laser beam emitted from such a laser device is widely used in various industrial fields because of its excellent characteristics according to monochromaticity, coherence and straightness. Particularly, the laser device can oscillate a laser beam capable of selectively absorbing, reflecting, and transmitting a target substance, and thus its usability is increasing in the medical industry.

Here, the laser device includes a light source and a resonator. The resonator includes a cavity, a laser medium, a High Resolution (HR) mirror, and an Output Coupler (OC) mirror. The laser beam oscillation is achieved by amplifying the light provided from the light source to the resonator by causing stimulated emission between the HR mirror and the OC mirror disposed across the laser medium.

On the other hand, the quality (intensity, wavelength, etc.) of the laser beam emitted from the laser device needs to consistently match the mutual structures between the light source and the resonator with respect to the optical axis on the optical path. An optical element position adjustment mount is used in such a configuration that these optical axis lines are matched. 1 to 3, the conventional optical element position adjusting mount 1 includes a holder 3 for supporting the optical element 2, an aligning portion 4, a guide portion 5, (6) and a guide pin (7).

More specifically, when the Z axis is an optical axis, the optical element position adjustment mount 1 moves the optical element 2 along the X axis and the Y axis. For example, the detailed operation is such that the guide pin 7 and the holder portion 7 between the aligning portion 4 and the holder portion 3, when the aligning portion 4 presses the holder portion 3 in the Y- The holder 3 is linearly moved through the guide pins 7 between the guide portions 3 and 3. At this time, the elastic member 6 provides the elastic force to the guide portion 5 so as to maintain the position of the moved holder portion 3.

However, the conventional optical element position adjusting mounts shown in Figs. 1 to 3 have the following problems.

First, because of the low machining accuracy of the insertion area of the guide pin, adjustability is reduced when the holder is moved in the X and Y axes.

Second, the X axis and the Y axis exist on the same plane, and when the X axis (or Y axis) of the holder is adjusted, the Y axis (or the X axis) moves together.

Third, the elastic force of the elastic member can be weakened with time, and when the elastic force is lowered, the moved initial position of the holder portion can be changed.
