    • Femtosecond pulse generation with a diode-pumped Yb3+:YVO4 laser 

      Kisel, V. E.; Troshin, A. E.; Shcherbitsky, V. G.; Kuleshov, N. V.; Matrosov, V. N.; Matrosova, T. A.; Kupchenko, M. I.; Brunner, F.; Paschotta, R.; Morier-Genoud, F.; Keller, U. (Optical Society of America, 2005)
      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 mirror for passive mode locking. The optical spectrum has a 10 nm bandwidth (full width at half-maximum) and is centered at 1021 nm.

    • Yb3+-doped YVO4 crystal for efficient Kerr-lens mode locking in solid-state lasers 

      Lagatsky, A. A.; Sarmani, A. R.; Brown, C. T. A.; Sibbett, W.; Kisel, V. E.; Selivanov, A. G.; Denisov, I. A.; Troshin, A. E.; Yumashev, K. V.; Kuleshov, N. V.; Matrosov, V. N.; Matrosova, T. A.; Kupchenko, M. I. (Optical Society of America, 2005)
      We report the first demonstration, to our knowledge, of soft-aperture Kerr-lens mode locking in a diode-pumped femtosecond Yb3+:YVO4 laser. Near-transform-limited pulses as short as 61 fs are generated around a center wavelength of 1050 nm with an output power of 54 mW and a pulse repetition frequency of 104.5 MHz. This is, to our knowledge, the shortest pulse generated directly ...
