Abstract: Laser diodes for pumping (3) are arranged around a reflector tube (2) which has narrow windows (14) facing the emission regions of these diodes and which leaves an annular gap (16) around a rod to be pumped (1). A cooling liquid traverses this gap. … The invention applies in particular to the optical pumping of a YAG rod. … …

Abstract: Power laser chain. Two amplifying elements are separated by a linear polarizer placed between two polarization transformers such as a quarter wave plate or a Fresnel parallelepiped, this preventing auto-oscillators in the amplifying chain, it being possible to repeat that sequence several times in the chain.

Abstract: 1526548 Lasers COMPAGNIE GENERALE D'ELECTRICITE SA 25 Oct 1976 [13 Nov 1975] 44209/76 Heading H1C In a laser pulse amplifying chain, spurious super radiant emission transmitted from one amplifier 7 to a succeeding amplifier 9 is suppressed by including a saturable absorber 3 and a monochromatic filter 5 between the amplifiers, the saturable absorber being responsive to at least one of the spectrol lines corresponding to a lasing transition in the amplifiers, and the filter allowing the passage of light pulses only of wavelengths corresponding to those lasing transition wavelengths initially absorbed in the saturable absorber. The absorbing composition may be sulphur hexafluoride gas optionally mixed with helium, while the filter consists of a blazed diffraction grating, a Fabry-Perot eterlon or a diffusion prism. In Fig. 3, which uses a diffraction grating 6 between CO 2 laser amplifiers 16 and 18, a saturable absorber 4 comprises an apertured gas filled cell 12 located at the focus of two spherical mirrors 8, 10.
