Semiconductor laser apparatus with isolator |
摘要 |
The apparatus includes a semiconductor laser diode, a mounting for the laser diode and a casing with a window through which light from the diode passes. The casing hermetically seals the diode. A magneto-optical member is provided between the end face of the laser diode and the window. The magneto-optical member has a spontaneous magnetization oriented in the direction of the light transmission and a magnetic field is applied to saturate the magneto-optical member.
