Title: Diaphragm for a laser amplifier chain
IPC: G02B5/00
Filed: 1969-07-23
Abstract: In a laser amplifier chain, a diaphragm formed of an apertured diverging lens 1 is placed between a driver laser (not shown) and an amplifying laser 4 to reduce deleterious effects caused by backwards radiation. The input face 5 of the driven laser rod 4 is cut at about 6 degrees to the axis 9 of the incident beam 31 to prevent reflection to the driver laser. The lens 1 diverts the outer portions of beam 31 to create a dead space 8 around face 5. To prevent radiation reflected from face 5 being focused on to the face by the curved lens surface 6, the lens may be tilted through some 10 degrees as in Fig. 2, focusing then being at P. The aperture in Fig. 2 may be circular or elliptical, and the edges thereof may be formed parallel to the axis 9. The lens is plano-concave, with its plane face towards the driver laser. The concave surface may be part spherical or part conical, and the lens material may be an attenuating glass. A diaphragm is preferably placed in front of each driven laser of the chain.
