Background technique
Optical cavity is the important component of laser oscillator.The effect of optical cavity is being to provide axial light wave mould just
Feedback and single mode (or a small number of axial modes) oscillation for guaranteeing laser.Two reflecting mirrors are properly placed at the both ends of gain media
Piece just constitutes a simplest optical resonator.What is proposed earliest in Development of Laser Technology history is plane-parallel resonator, it by
Two pieces of plane-parallel mirror compositions.
Laser oscillator for the laser resonator constituted using flat-flat mirror, to make system run on absolute ideal
State be not easy very much because it is very difficult that two optical cavity hysteroscopes, which are registered to strictly parallel,.In addition to this
The horizontal and vertical mobile range of optical cavity hysteroscope is limited by the geometric dimension of hysteroscope.When optical cavity hysteroscope by
When small disturbance, the laser power of output, which can significantly shake, even interrupts laser output.These problems limit laser
Application of the oscillator in many fields.Especially for the easy alignment using laser oscillator optical cavity in many fields,
Mobility and power stability are all extremely important.
In order to improve the controllability and output power stability of laser oscillator, Pu Luoleng is generallyd use in the prior art
Mirror or prism of corner cube replace plane mirror as the retro-reflection mirror in laser resonator.Although prism of corner cube may be implemented
Stability and the freely regulated function of angle, but two problems are still had in actual use:
One, the vertex of prism of corner cube is not effective reflection point, so the point can not reflect incident laser beam.Therefore
The center of the beam profile of the laser oscillator output of this structure can have a stain；
Two, mismachining tolerance small between three reflectings surface of prism of corner cube will will lead to very big laser power damage
Consumption.Laser oscillator will be made to fail the laser system above-mentioned two problems bring loss of low gain.
Opal Reflex Reflector has been used in He-Ne laser as retro-reflection mirror in the prior art, can solve
The angular adjustability of laser and the traditional problem of power stability.But two kinds of above-mentioned solutions remain that reply is anti-
Emitter may only realize the angular adjustability around central axes in alignment on the central axes line of system.Therefore, it is necessary to more
Simple and effective optical cavity scheme realizes easy alignment, moves, the laser oscillator of high stability.
Summary of the invention
Present invention aims to overcome that the limitation of above-mentioned existing laser oscillator, provides a kind of easily alignment, moves, it is high
The optical cavity of power stability may be implemented the easy alignment of laser oscillator, can move freely adjusting in visual field scope
And high output power stability.It is not only easy to operate, scientific and effective but also practical.
The principle of the present invention is:
Total reflection mirror and the first lens constitute the telecentricity cat eye structure that is all-trans, and focal point, which forms one, has one
Determine the pupil 1 of field angle.It can be along road identical with incident beam by the light beam that the pupil enters the telecentricity cat eye structure that is all-trans
Diameter returns.Pupil 1 and the first lens, the distance between the first lens and total reflection mirror are equal to the focal length of the first lens, this is complete
Anti- telecentricity cat eye structure is equivalent to a 4f imaging system, will not influence steady area's range of laser resonator.Second lens with it is defeated
Coupling mirror constitutes an output telecentricity cat eye structure out, and focal point forms the pupil 2 with certain visual angle.Through
It crosses the pupil and enters beam section edge path identical with the incident beam returning part of output telecentricity cat eye structure by output
Coupling mirror realizes laser output.Pupil 2 and the second lens, the distance between the second lens and output coupling mirror are equal to second thoroughly
The focal length of mirror, the output telecentricity cat eye structure are equivalent to a 4f imaging system, will not influence steady area's range of laser resonator.
