What is claimed is:
1. A light adjustment device for a laser resonant docket, comprising:
a laser base having a housing that defines a laser chamber that retains a laser diode therein, and a fixing seat disposed at one end of the housing;
an upper cover that is removably coupled with the fixing seat to define a spherical groove; and
an adjuster body, having a ball and an adjusting shaft, wherein a resonant socket room is defined in the ball, with a laser resonant socket retained inside the socket room;
wherein the ball is seated inside the spherical groove in a manner such that the ball can be pivoted inside the spherical groove to adjust the orientation of the ball and the adjusting shaft with respect to the laser base.
2. The device of claim 1, wherein the ball of the adjuster body is formed by cutting two opposing planar portions thereof, and has two openings, one opening at each of the planar portions of the ball for accessing the socket room.
3. The device of claim 2, wherein the adjusting shaft has a hollow section and is connected to one of the two planar portions so as to allow a laser beam emitted from the laser resonant socket to project through the hollow section thereof.
4. The device of claim 2, wherein a slot is disposed in the ball, the slot being cut from an outer surface of the ball through to the resonant socket room, and further including a resonant socket-fixing sheet that is inserted into the slot to fix the position of the laser resonant socket.
5. The device of claim 3, further including a lens set positioned inside the hollow section of the adjuster shaft.
6. The device of claim 1, wherein a slot is disposed in the ball, the slot being cut from an outer surface of the ball through to the resonant socket room, and further including a resonant socket-fixing sheet that is inserted into the slot to fix the position of the laser resonant socket.
7. The device of claim 1, wherein the upper cover is coupled to the fixing seat of the laser base by bolts.
8. The device of claim 1, wherein the fixing seat of the laser base defines a semi-spherical groove.
9. The device of claim 8, wherein the upper cover defines a semi-spherical groove.
10. A method of adjusting a laser resonant socket, comprising:
providing a laser base having a housing that defines a laser chamber that retains a laser diode therein, and a fixing seat disposed at one end of the housing;
providing an adjuster body having a ball and an adjusting shaft, the ball defining a resonant socket room therein;
positioning a laser resonant socket into the resonant socket room;
placing the ball on the fixing seat and pivoting the ball until a desired orientation is reached; and
placing an upper cover over the ball and the fixing seat, and securing the upper cover to the fixing seat.
11. The method of claim 10, wherein the fixing seat defines a semi-spherical groove on which the ball is received and pivoted.
12. The method of claim 11, wherein the upper cover defines a semi-spherical groove which combines with the semi-spherical groove of the fixing seat to form a spherical groove inside which the ball is retained.
