Polarized cw and time-resolved excited-state absorption spectra were measured in Cr 4+ -doped Mg 2 SiO 4 in the 200–2200 nm spectral region. Polarization-dependent excited-state absorption was observed in the infrared due to the 3 T 2 → 3 T 1a tr

A diode-pumped Yb:YVO4 laser has been passively mode locked for the first time, to our knowledge. 120 fs pulses with an average output power of 300 mW and a peak power as high as 14.5 kW are obtained by use of a semiconductor saturable-absorber mirro
