Combining high power femtosecond laser system and high harmonics generation, femtosecond enhancement cavity (fsEC) has been established as one of most effective method to transfer near-infrared laser source, which can be built up easily, to Deep Ultraviolet (DUV) or Vacuum Ultraviolet (VUV) region, while inheriting the full repetition rate from the oscillator, which is typically on the order of 10 MHz - 100 MHz.
In turn, high repetition rate DUV or VUV laser source can greatly drive the development of photoemission spectroscopy.
Currently, we are focusing on how to achieve higher output power and maintain longer term operation using our specially developed enhancement cavity, that features only 4 mirrors and a total cavity length of 30-m.
