Paper Abstract

In this paper, we present different procedures of laser conditioning realized on KDP doubler crystals. First, components are treated either with an excimer laser (SOCRATE facility, 351 nm, 12 ns) or a Nd: YAG laser (MISTRAL facility, 355 nm, 7 ns). Then damage tests are performed at 2ω (532 nm - 5 ns BLANCO facility) and 3ω (355 nm - 2.5ns LUTIN facility) in order to estimate the conditioning gain for these two wavelengths. For the best procedures, results show that it is possible to increase laser damage threshold at 532 nm so that it becomes compatible with the nominal specifications of the LMJ. Moreover, tests realized at 355 nm highlight also an encouraging improvement for the laser conditioning of tripler crystals.
