The rings are in contact with the support, and a stack of diodes, called bottom stack, being situated between the rod and the support, and the structure comprises, for each other stack, a thermal conduction block forming a support for said stack, these blocks being mounted on the cooled support and not being in contact with one another or with the rings. | 09-29-2011 |
20120263199 | Laser Emitting Pulses of Variable Period and Stabilized Energy - A laser device suitable for emitting pulses with a variable period and with stabilized energy includes: a resonant cavity including an amplifying medium presenting a stabilized gain G and suitable for emitting laser pulses at a wavelength λ, and a Q-switch, and a source of continuous pumping of the amplifying medium. It furthermore includes an injector positioned outside the resonant cavity, suitable for emitting a beam of wavelength λ into the amplifying material for the duration of the pumping, and which includes means for adjusting the power of this beam in order to reduce the gain of the amplifying medium to G/k, where k is a real number greater than 1. | 10-18-2012 |
