Abstract

PURPOSE: To make easy the coupling with optical fiber and the detection of monitor light, by providing the center of the emitting window of main laser light and monitor light on one optical axis vertical to the bottom surface, and forming the cap bottom and the screw part cocentrically.
CONSTITUTION: The screw 4 having the hollow part 3 is placed at the center of the bottom 1 made of kovar cocentrically with the bottom 1 with common center axis, and the hole 2 is made at the bottom 1 so that the center shaft is in agreement with the screw 4. The hole 10 is made at the center of the cap 9 so arranged that the it is in agreement with the center line 5, and the sapphire plate 11 optically polished for the both sides parallelly and smoothly is sealed with solder inside of it. The both laser lights of the main beam 14 and monitor 15 radiated from the laser crystal 13 are determined so that they are in agreement with the center line 5 for the direction and the size of heat sink 12 and radiator 6. The electrode of the crystal 13 is connected to the bottom 1 and the kovar made pole.
