    "abstract": "We report on new simple and efficient multipass amplifiers using prisms or\ncorner cubes to perform several passes in different planes of incidence. This\nscheme provides an optimized overlap between the signal passes and the pumped\nvolume. We investigated our amplification geometry with Nd:YAG and Nd: YVO4\ncrystals : the use of a low doped (0.3%) Nd:YVO4 crystal allowed better thermal\nbehaviour and higher performances. We amplified a pulsed microlaser (110 mW of\naverage power at 1064 nm) and obtained a diffraction-limited output beam with\nan average power of 5.7 W for 15 W of pump power and a small-signal gain of 56\ndB in a 6-pass configuration.",
