Abstract

The present disclosure is intended to provide a smaller laser oscillator that can be manufactured at a reduced cost. Provided is a laser oscillator for producing a laser beam, the laser oscillator including: a housing; a transformer arranged in the housing, connected to a power supply, and supplying power to a first device that consumes a predetermined amount of power; and a power factor correction unit arranged in the housing, having a power factor correction circuit that brings a power factor close to 1, connected to the power supply, and supplying power to a second device that consumes a relatively larger amount of power than the first device.

First claim

What is claimed is:

1. A laser oscillator for producing a laser beam, the laser oscillator comprising:
a housing;
a transformer arranged in the housing, connected to a power supply, and supplying power to a first device that consumes a predetermined amount of power; and
a power factor correction unit arranged in the housing, having a power factor correct on circuit that brings a power factor close to 1, connected to the power supply, and supplying power to a second device that consumes a relatively larger amount of power than the first device.

2. The laser oscillator according to claim 1 , wherein
the first device includes at least a dehumidifier, a control power supply, a safety circuit, a contactor coil, a 24 V power supply unit, or a fan motor.

3. The laser oscillator according to claim 1 , wherein
the second device includes at least an oscillation fiber, a laser diode that causes excitation light to be incident on the oscillation fiber, or a laser diode power supply that supplies power to the laser diode.
