Abstract

A fiber laser oscillator includes a housing that accommodates an optical unit such that the optical unit is able to be drawn out of the housing; and a clean bench that is detachable to a side of the optical unit, and defines a closed space which is isolated from outside, in which a communication opening that is in communication with an internal space of the housing is defined in the clean bench.

First claim

What is claimed is:

1. A fiber laser oscillator including an optical unit which has a fusion splicing part in which optical fibers are to be joined, the fiber laser oscillator comprising:
a housing that accommodates the optical unit such that the optical unit is able to be drawn out of the housing; and
a clean bench that is detachable to the housing or a side of the optical unit, and defines a closed space which is isolated from outside,
wherein:
a communication opening that is in communication with an internal space of the housing is defined in the clean bench,
the optical unit is able to move in and out of the housing independently of the clean bench,
the clean bench is above the optical unit in a first state in which the optical unit is drawn out from the housing, and
the clean bench is removed from the housing in a second state in which the optical unit is inside the housing.

2. The fiber laser oscillator according to claim 1 , further comprising:
a humidity detection part configured to detect humidity inside of the clean bench; and
a control unit configured to determine whether the fiber laser oscillator is operable based on a detection value of the humidity detection part.

3. The fiber laser oscillator according to claim 1 , further comprising a base plate configured to fix the optical unit,
wherein:
the base plate can be drawn out from the housing, and
the clean bench is attached to the base plate.

4. The fiber laser oscillator according to claim 1 , wherein the clean bench has a visible light transmissive part.

5. The fiber laser oscillator according to claim 1 , wherein the clean bench has a curtain part constituted by a material that is visible light transmissive and flexible, at an outside surface which is different from a portion in contact with the housing.

6. The fiber laser oscillator according to claim 1 , wherein the clean bench is able to have a shelf disposed at an interior or exterior thereof.

7. A clean bench that is detachable to a fiber laser oscillator including an optical unit having a fusion splicing part in which optical fibers are to be joined and a housing that accommodates the optical unit such that the optical unit is able to be drawn out of the housing,
wherein:
the clean bench defines a closed space isolated from outside,
a communication opening that communicates with an internal space of the housing is defined in the clean bench,
the optical unit is able to move in and out of the housing independently of the clean bench,
the clean bench is above the optical unit in a first state in which the optical unit is drawn out from the housing, and
the clean bench is removed from the housing in a second state in which the optical unit is inside the housing.

8. The fiber laser oscillator according to claim 1 , further comprising an air conditioner,
wherein:
the air conditioner is positioned at the housing, and
the air conditioner is configured to perform:
air-conditioning inside of the housing, and
air-conditioning inside of the clean bench through the communication opening.

9. The fiber laser oscillator according to claim 8 , wherein the air conditioner is further configured to perform dehumidification inside of the optical unit in the first state in which the optical unit is drawn out from the housing.

10. The clean bench according to claim 7 , wherein:
an inside of the housing is configured to be air-conditioned by an air conditioner, and
an inside of the clean bench is configured to be air-conditioned by the air conditioner through the communication opening.

11. The clean bench according to claim 10 , wherein an inside of the optical unit is configured to be dehumidified by the air conditioner in the first state in which the optical unit is drawn out from the housing.
