Abstract

We have developed the first (to our knowledge) femtosecond Tm-fiber-laser-pumped Ho:YAG room-temperature chirped pulse amplifier system delivering scalable multimillijoule, multikilohertz pulses with a bandwidth exceeding 12 nm and average power of 15 W. The recompressed 530 fs pulses are suitable for broadband white light generation in transparent solids, which makes the developed source ideal for both pumping and seeding optical parametric amplifiers operating in the mid-IR spectral range.

Supercontinua (patterned red area) generated in different transparent solids (indicated in the panels). The shaded area is the transmission of the mirror cutting the fundamental 2.1 μm light. The filled blue area represents the output spectrum of the Ho:YAG CPA system. In the insets, photographs of the generated supercontinua are presented. Spectra in the visible and IR spectral ranges, measured respectively with HR4000 and NIRQuest512 spectrometers (Ocean Optics), are independently normalized. The detection limit of our NIRQuest512 spectrometer lies at 2550 nm.
