摘要：

We present experimental results that showhow diode-pumped Tm:YLF can be used to develop the next generation of laserswith high peak andhigh average power. Wedemonstrate the production of broad bandwidth, lambda approximate to 1.9 mu mwavelength, 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 similar to 50 mu J pulses to the Joule-level. Furthermore, we show the average power capability of this material in a heliumgas-cooled amplifier head, achieving a heat removal rate almost 10 times higher than the state-of-the-art, surpassing 20 W/cm(2). These demonstrations illustrate the capabilities of directly diode-pumped Tm:YLF to support TW to PW-class lasers at kW average power.
