Partial reflective laser output device |
摘要 |
A partial reflective laser output device comprising a partial reflective unit mounted on a laser output device (such as a vertical cavity emitting laser), the partial reflective unit allowing the laser beam emitted from the laser output device to be partially reflected while the rest penetrating through. On one hand, this device decreases the intensity of output laser light so as to comply with the eye safety standard; the reflected light is absorbed by a photodiode (PD) to perform auto power control on the laser output device on the other. In addition, by adjusting the tilting angle of the partial reflective unit or making a curvature thereon, the reflected light can have no destructive interference with the output light and can even be focused onto the PD so that there would be no relative intensity noise problem and the size of the PD can be made smaller to lower the cost.
