Title:
SEMICONDUCTOR LASER DEVICE WITH OPTICAL FIBER
Document Type and Number:
Japanese Patent JPH01142512
Kind Code:
A
Abstract:
PURPOSE:To produce a semiconductor laser with an optical fiber without using a special assembling device by adjusting and fixing a ferrule of an optical fiber assembly inserted into the central hole of a holder by means of plural pieces of screws directed to the central direction in such a manner that the center at the end part of the optical fiber aligns to the beam waist of laser light. CONSTITUTION:This laser device has the holder 6 which supports a semiconductor laser 1 and releases the focused laser light in the optical axis direction and the optical fiber assembly consisting of the optical fiber 8 and the ferrule 9 holding the fiber. The device is constituted by adjusting and fixing the ferrule of the optical fiber assembly inserted into the central hole of the holder 6 by means of plural pieces of the screws 7 directed toward the central direction in such a manner that the center at the end of the optical fiber 8 aligns to the beam waist of the laser light. The semiconductor laser device with the optical fiber which can be produced without using techniques such as welding is thus obtd. by the simple constitution to allow the easy alignment of the optical axis.
