    • Passive mode locking of 2.09 μm Cr,Tm,Ho:Y3Sc2Al3O12laser using PbS quantum-dot-doped glass 

      Denisov, I. A.; Skoptsov, N. A.; Gaponenko, M. S.; Malyarevich, A. M.; Yumashev, K. V.; Lipovskii, A. A. (Optical Society of America, 2009)
      Passive Q-switched mode locking of a 2.09 μm flashlamp-pumped Cr3+,Tm3+,Ho3+:Y3Sc2Al3O12 laser by use of a phosphate glass doped with PbS quantum dots of 5 nm in radius was demonstrated. Mode-locked pulses of 290 ps in duration and up to 0.5 mJ in energy were registered.

    • 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 ...
