Abstract

We report an increase in pulse energy to 5.1 μ J obtained directly from a femtosecond diode-pumped Yb : YAG thin disk laser without external amplification. Stable passive mode locking was obtained with a semiconductor saturable absorber mirror (SESAM). The laser delivers 63 W of average output power in a nearly diffraction-limited beam ( M 2 = 1.1 ) at a center wavelength of 1030 nm . The pulse repetition rate is 12.3 MHz , and the pulses have a duration of 800 fs , which results in a peak power of 5.6 MW . The laser was operated in a box flooded with helium because the nonlinearity of air was found to be a limiting factor for the stability of the pulse formation at increasing pulse energies.
