We demonstrate a versatile tunable and highly stable ultrabroadband Ti:sapphire chirped pulse amplification system with a compressed pulse energy of 20 mJ at 100 Hz repetition rate. High power Ti:Sa systems in principle do not offer wavelength tunability due to gain narrowing. Here we demonstrate transform limited pulse generation from 15 fs to 94 fs with tunable central wavelength (λc from 755 nm to 845 nm) and bandwidth (130 nm<Δλ<16 nm) as well as multi-color, time synchronized, sub-100 fs pulses with user defined central wavelength separation. The unique wavelength tunability capabilities have been expanded into the UV and deep-UV by second and third harmonic generation with excellent energy stability. Enhanced energy stability is achieved by multiplexing six ultrastable diode-based solid state pump lasers.
我们展示了一种多功能、可调谐且高度稳定的超宽带钛宝石啁啾脉冲放大系统，其在100 Hz重复频率下的压缩脉冲能量为20 mJ。由于增益窄化，高功率钛宝石系统原则上不具备波长可调性。在此，我们展示了从15 fs到94 fs的变换极限脉冲产生，其中心波长（λc从755 nm到845 nm）和带宽（130 nm <Δλ< 16 nm）可调，以及具有用户定义中心波长间隔的多色、时间同步、亚100 fs脉冲。通过二次和三次谐波产生，独特的波长可调性能力已扩展到紫外和深紫外区域，且具有出色的能量稳定性。通过复用六个基于超稳定二极管的固态泵浦激光器实现了增强的能量稳定性。
