15 October 2015Direct liquid cooled Nd:YLF thin disk laser with unstable resonator
A large-aperture Nd:YLF thin disk laser oscillator is demonstrated, in which the refractive index matching liquid is used as the coolant flowing in narrow channels to cool the multiple thin disks directly. A high uniformity of pump intensity distribution is realized by using waveguides. With the a-cut Nd:YLF thin disks at different doping levels, a linearly polarized laser with the maximum output energy of 346 mJ is achieved with the repetition of 350 Hz, corresponding to an optical-optical efficiency of 8.7%, and a slope efficiency of 10%. The beam quality β factor is estimated less than 8 in the horizontal direction due to the positive branch confocal unstable resonator. To the best of our knowledge, it is the first time that the direct-liquid-cooled Nd:YLF thin disk unstable resonator is reported.
