We report the amplification of laser pulses at a center wavelength of 1034 nm to an energy of 16.6 J from a fully diode-pumped amplifier using Yb:CaF2 as the active medium. Pumped by a total optical power of 300 kW from high-power laser diodes, a gain factor of g=6.1 was achieved in a nine-pass amplifier configuration agreeing with numerical simulations. A measured spectral bandwidth of 10 nm full width at half-maximum promises a bandwidth-limited compression of the pulses down to a duration of 150 fs. These are, to our knowledge, the most energetic laser pulses achieved from a diode-pumped chirped-pulse amplifier so far.
我们报道了使用Yb:CaF2作为激活介质的全二极管泵浦放大器，将中心波长为1034 nm的激光脉冲放大至16.6 J的能量。由高功率激光二极管提供的300 kW总光功率泵浦，在九通放大器配置中实现了增益因子g = 6.1，这与数值模拟结果相符。测得的半高全宽为10 nm的光谱带宽预示着脉冲可进行带宽受限压缩，直至持续时间达到150 fs。据我们所知，这些是迄今为止从二极管泵浦啁啾脉冲放大器获得的能量最高的激光脉冲。
