    • Diode-pumped passively mode-locked Er,Yb:YAl3(BO3)4laser at 1.5-1.6 μm 

      Lagatsky, A. A.; Kisel, V. E.; Troshin, A. E.; Tolstik, N. A.; Kuleshov, N. V.; Leonyuk, N. I.; Zhukov, A. E.; Rafailov, E. U.; Sibbett, W. (2008)
      We report the first demonstration to our knowledge of passive mode locking in a diode-pumped Er3+ and Yb3+ codoped YAl3(BO3)4 laser operating in the 1.5-1.6 μm spectral region. Low-loss GaInNAs quantum-well semiconductor saturable absorber mirrors are used for the initiation and stabilization of the ultrashort-pulse generation. Pulses as short as 4.8 ps were generated at 1530 nm ...

    • Efficient 1 W continuous-wave diode-pumped Er,Yb:YAl3(BO3)4 laser 

      Tolstik, N. A.; Kurilchik, S. V.; Kisel, V. E.; Kuleshov, N. V.; Maltsev, V. V.; Pilipenko, O. V.; Koporulina, E. V.; Leonyuk, N. I. (Optical Society of America, 2007)
      We report the spectroscopy and high-power continuous-wave (CW) diode-pumped laser operation of Er:Yb:YAl3(BO3)4 crystal. Absorption and stimulated emission spectra, emission lifetimes, and efficiency of energy transfer from Yb3+ to Er3+ ions were determined. A CW Er:Yb:YAB laser emitting at 1602, 1555, and 1531 nm with output power as high as 1 W and slope efficiency up to 35% ...

    • Highly efficient continuous-wave diode-pumped Er, Yb:GdAl3(BO3)4 laser 

      Kisel, V. E.; Gorbachenya, K. N.; Yasukevich, A. S.; Maltsev, V. V.; Leonyuk, N. I.; Kuleshov, N. V. (Optical Society of America, 2013)
      We report the highly efficient continuous-wave diode-pumped laser operation of Er, Yb:GdAl3 BO3 4 crystal. Absorption and stimulated emission spectra, emission lifetimes, and efficiencies of energy transfer from Yb3 to Er3 ions were determined. A maximal output power of 780 mWwas obtained at 1531 nm at absorbed pump power of 4 W with slope efficiency of 26%.

    • Laser Performance of Er,Yb:YAl3(BO3)4 Crystals with Different Erbium Concentrations 

      Gorbachenya, K. N.; Kisel, V. E.; Yasukevich, A. S.; Maltsev, V. V.; Leonyuk, N. I.; Kuleshov, N. V. (2014)
      The effect of erbium concentration on the laser performance of Er,Yb:YAl3(BO3)4 crystals was investigated. A maximal output power of 1.6 W in CW and 2.7 W in QCW regimes was obtained at 1522 nm.
