LASER
Document Type and Number:
Japanese Patent JPH03181187
Kind Code:
A
Abstract:
PURPOSE: To obtain a high output compact laser by providing a plurality of partial sections, and optical coupling sections to be coupled each other through a deflection mirror and arranging the partial parts only in the radial direction with respect to a common center. CONSTITUTION: As shown by an arrow 18, the beam path of a resonator 1 starts from an end mirror 16 and passes through two partial sections 4 arranged linearly while intersecting the center of beam 6 before being deflected from a mirror 10 along an optical coupling section 12. It is then reflected again clockwise by an angular interval α on the mirror 10 and extends along other two partial sections 4 while intersecting a new center beam 6. The regressive pattern continues until it reaches a beam transmitting resonator mirror partially. A laser medium is excited only in the region of partial sections 4, 4' and not excited in the region of the section 12. Since thermal expansion takes place in the radial direction at the time of laser excitation, the angular interval αis varied only slightly thus eliminating the need of adjusting the resonator beam.
