Method for realizing all-fiber package of semiconductor saturable absorption mirror

Abstract

The invention discloses a method for realizing an all-fiber package of a semiconductor saturable absorption mirror. The method comprises the following steps of: uniformly spreading ultraviolet glue on the upper surface of a ceramic fiber pin except for the part of the head face of a fiber core; slowly placing a semiconductor saturable absorption mirror which is not packaged on the upper surface of the ceramic fiber pin of a fiber ferrule connector (FC) joint horizontally; and connecting a fiber at the other end of the fiber FC joint in a cavity of a fiber laser. The semiconductor saturable absorption mirror or the fiber FC joint can be changed when experiments show that parameters of the placed semiconductor saturable absorption mirror of the model fail to satisfy the experiment requirements or show that the head face of a fiber core corresponding to the semiconductor saturable absorption mirror is damaged in the experiment process; and the ultraviolet glue can be adopted to cure when the experiments provs that the various parameters of the semiconductor saturable absorption mirror are accordant with the requirements. The method provided by the invention breaks through the technological monopoly at home and abroad, and is simple in operation, low in cost and excellent in repeatability; and the method fills the blank in the technical field at home.

Problems solved by technology

[0006] The semiconductor saturable absorber mirror packaged with a copper base is cheap, and the semiconductor saturable absorber mirror has a large area, which can provide multiple chances of damage; but it is used in a passive mode-locked fiber laser. Two precise three-dimensional adjustment brackets are required for the fiber respectively. The semiconductor saturable absorbing mirror packaged with a copper base is fixed and adjusted. In addition, a pair of lenses are required for coupling. The overall required components are many, the structure is complex, the price is expensive, the adjustment skills are high, and the overall volume is large. Inconvenient to integrate, unable to take advantage of the advantages of small size and low price of fiber lasers
