Journal ArticleDOI
Generation of spatially incoherent short pulses in laser-pumped neodymium stoichiometric crystals and powders
TL;DR: In this paper, the authors developed mirrorless quasi-monochromatic laser sources made of stoichiometric neodymium compounds (Nd0.75:La0.25P4O15 and NdCl3· 6H2O) pumped by nanosecond laser pulses and found that short sub-nanosecond and narrowbandwidth (0.15-nm) pulses are generated in both compounds when they are pumped at high intensities.
Journal ArticleDOI
Optical spatial smoothing of Nd-Glass laser beam
Didier Veron,H. Ayral,C. Gouedard,D. Husson,J. Lauriou,O. Martin,B. Meyer,M. Rostaing,C. Sauteret +8 more
TL;DR: In this paper, a broadband oscillator and an optical fiber are used as dispersing elements in the pulse generator of the laser chain for smoothing a Nd-glass laser beam.
Journal ArticleDOI
Statistical analysis for beam smoothing and some applications
TL;DR: In this article, the performance of spectral dispersion and optical fiber smoothing is analyzed in the asymptotic framework of a large number of elements of the random-phase plate and of excited optical modes of the fiber.
Journal ArticleDOI
Optical smoothing of the high power PHEBUS Nd-glass laser using the multimode optical fiber technique
TL;DR: In this paper, the authors used an optical fiber for the coherence reduction at the laser front-end, which changes the common point laser source into an extended source, and the required optical arrangement taking into account the divergence of the extended source beam is described.
Journal ArticleDOI
Propagation and amplification of incoherent pulses in dispersive and nonlinear media
TL;DR: In this paper, a statistical model was developed to study all the relevant phenomena that can give rise to an anomalous intensity saturation in the propagation of incoherent pulses in a laser amplifier.
