The sudden translation at a continuous speed of the laser rod inside a single-mode standing-wave laser results in a transient oscillation of the output intensity. Using a first-order analytical rate equation model, the analysis of this transient behavior gives the values of the diffusion constant of the excited states, and of the upconversion Auger rate. We performed these measurements in a 1% doped...
The reduction of the number of oscillating modes by a self-adapted Fabry–Perot (FP) filter was first demonstrated in a dye laser in 1987 [Opt. Lett. 12 (1987) 117]. A renewal of interest in this technique arose recently with the observation of a dramatic reduction of the number of modes in a pulsed Sapphire:Ti laser [Appl. Phys B 69 (1999) 155]. A self-adapted Fabry–Perot filter is made of a photorefractive...
