Abstract: An inexpensive solid laser oscillator from which high output can be obtained. Laser crystals (YAG laser crystals, etc.) (1a, 1b and 1c) are so arranged along the optical axis of an optical resonator that the crystals are in optical contact with each other. Adjacent laser crystals have surfaces facing to each other with adhesive layers (10, 20) inbetween and form a linear aggregate as a whole. The adhesive of the adhesive layers exhibits a low light absorption factor for light having the oscillation wavelength of the laser oscillator or pumping light. When the refractive index of the adhesive is nearly equal to that of the laser crystals, optical matching can be obtained. The adhesive layers (10 and 20) can be formed of another transparent material or can be replaced with narrow gaps or face-contacts.

Abstract: A laser oscillator which establishes r-f discharge by applying an r-f voltage to a plurality of discharge regions via a dielectric member in order to realize laser oscillation. The laser oscillator consists of a DC power source (16) and r-f power sources (18, 19, 20, 21) that convert a DC voltage into an r-f voltage. The DC power source (16) and the r-f power sources (18, 19, 20, 21) are coupled together via a filter (30). The filter (30) prevents r-f components from being fed back from the r-f power sources (18, 19, 20, 21), thus keeping the laser oscillator from unstable operation due to parasitic oscillation. Means is further provided to prevent interference between the r-f power sources and the DC power source.

Abstract: In a blower for forcibly circulating a laser gas in a gas laser, a shaft (2) of a vane wheel (1) is mounted with an intermediate member (66) which is rotatable therewith, and rings (641, 642) are fitted in annular grooves (651, 652) formed in the intermediate member (66). A ring holder (63) an inner surface of which is always kept in contact with outer circumferential surfaces of the rings (641, 642) is provided on a bearing holder (60) retaining a bearing (5) which supports the shaft (2). Consequently, gaseous impurities passing through the bearing (5) and flowing toward a gas laser circulating passage positioned on the upper side thereof are blocked owing to a narrow axial clearance between the rings (641, 642) and annular grooves (651, 652).

Abstract: This invention relates to a NC laser apparatus comprising the combination of a numeric control apparatus and a laser machining apparatus. It includes a means for measuring the oscillation time of laser and a means (19) for measuring laser output power. When the oscillation time is within a predetermined time based on the life of optical components and the drop rate of the output power is below a predetermined value, an instruction for cleaning optical components is displayed on a display (18). When the oscillation time of the laser exceeds a predetermined time and the drop rate of the output power is below the predetermined value, an instruction to replace the optical components (5, 6) is displayed on the display (18). Accordingly, the maintenance becomes easy and the life of the optical components can be improved.
