Measurements of the free running carrier envelope offset frequency (fceo) linewidth of a similariton based optical frequency comb show that the frequency noise of the laser is independent of net cavity dispersion.
A Yb rod amplifier that generates 2.7 ps pulses with 55 W power at 50 MHz repetition rate is reported. Amplified pulses exhibit minimal spectral distortion and high beam quality. Frequency-doubling yields 35 W green power.
A fiber amplifier that achieves sub-picosecond pulse duration and greater than 100 W average power at 1.3-GHz repetition rate is reported. Frequency-doubling of the amplified pulses yields 65 W green power.
