Abstract

Power scaling high repetition-rate ultra-short-pulse lasers, operating in the atmospheric transmission window beyond 2.0 μm, may offer new defence capabilities, provide efficient non-linear conversion to 3-5 μm, and will enable interesting high power ultra-fast laser-matter interaction studies. Our system consists of a commercial mode-locked laser oscillator operating at a central wavelength of 2.090 μm, coupled into a 28-times-gain Ho:YAG rod double-pass pre-amplifier, as well as a high-power Ho:YAG slab amplifier, itself pumped by an in-house developed 300W-class Tm:YLF slab laser. We will be presenting our experimental power scaling results, alongside ultra-fast laser-matter interaction studies on relevant infrared materials, including silicon, germanium, ZnSe and GaAs.
