Title: The Net Gain Bandwidth Broadening in Yb-doped Laser Materials-A Breakthrough in Obtaining High-energy Pulses of Extremely Short Duration. Applicants. Abstract: Since Yb-based laser materials were established as an alternative to Ti-Sapphire for ultrafast laser development in the late 1990s, tremendous progress has been made in generating ultrashort pulses with record-high energies or average powers. Although the Yb femtosecond oscillator architectures …
