Abstract

We present experimental results that show how diode-pumped Tm:YLF can be used to develop the next generation of lasers with high peak and high average power. We demonstrate the production of broad bandwidth, λ≈ 1.9 μm wavelength, high energy pulses with up to 1.6 J output energy and subsequent compression to sub-300 fs duration. This was achieved using a single 8-pass amplifier to boost stretched approximately 50 μJ pulses to the Joule-level. Furthermore, we show the average power capability of this material in a helium gas-cooled amplifier head, achieving a heat removal rate almost ten times higher than the state-of-the-art, surpassing 20 W/cm². These demonstrations illustrate the capabilities of directly diode-pumped Tm:YLF to support TW to PW-class lasers at kW average power.
