Laser oscillator unit and laser machining device

A laser oscillator unit comprising:

• an amplification unit configured to amplify incident laser light and emit amplified laser light from an emitting portion;
• a case covering the amplification unit;
• an outer support mechanism provided outside the case and supporting the case with respect to a base;
• and
• an inner support mechanism provided inside the case and supporting the amplification unit with respect to the case,
• wherein the case is formed with a window portion that outputs the laser light emitted from the emitting portion to an outer side of the case by spatial transmission,
• wherein the outer support mechanism comprises:
• an outer fixed leg that is fixed to the base and the case;
• and
• a plurality of outer movable legs that slidably support the case with respect to the base,
• wherein at least one outer movable leg of the plurality of outer movable legs allows the case to slide in a radial direction around the outer fixed leg,
• wherein the inner support mechanism comprises:
• an inner fixed leg that is fixed to the amplification unit and the case;
• and
• a plurality of inner movable legs that slidably support the amplification unit with respect to the case,
• wherein at least one inner movable leg of the plurality of inner movable legs allows the amplification unit to slide in a radial direction around the inner fixed leg, and
• wherein a straight line passing through a center of the outer fixed leg and a center of the inner fixed leg intersects with a straight line passing through the emitting portion and the window portion, and a laser optical axis emitted from the emitting portion and a laser optical axis emitted from the window portion coincide with each other.
