    • 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% ...

    • Energy transfer in Tm,Ho:KYW crystal and diode-pumped microchip laser operation 

      Kurilchik, S. V.; Gusakova, N. V.; Demesh, M. P.; Yasukevich, A. S.; Kisel, V. E.; Pavlyuk, A. A.; Kuleshov, N. V. (Optical Society of America, 2016)
      An investigation of Tm-Ho energy transfer in Tm(5at.%), Ho(0.4at.%):KYW single crystal by two independent techiques was performed. Based on fluorescence dynamics measurements, energy transfer parameters P71 and P28 for direct (Tm→Ho) and back (Ho→Tm) transfers, respectively, as well as equilibrium constant Θ were evaluated. The obtained results were supported by calculation of ...

    • Femtosecond pulse operation of a Tm,Ho-codoped crystalline laser near 2 μm 

      Lagatsky, A. A.; Fusari, F.; Calvez, S.; Kurilchik, S. V.; Kisel, V. E.; Kuleshov, N. V.; Dawson, M. D.; Brown, C. T. A.; Sibbett, W. (Optical Society of America, 2010)
      We demonstrate, for the first time to our knowledge, femtosecond-regime mode locking of a Tm,Ho-codoped crystalline laser operating in the 2 μm spectral region. Transform-limited 570 fs pulses were generated at 2055 nm by a Tm,Ho:KY(WO4)2 laser that produced an average output power of 130 mW at a pulse repetition frequency of 118 MHz. Mode locking was achieved using an ion-implanted ...

    • Laser performance of in-band pumped Er : LiYF4 and Er : LiLuF4 crystals 

      Gorbachenya, K. N.; Kurilchik, S. V.; Kisel, V. E.; Yasukevich, A. S.; Kuleshov, N. V.; Nizamutdinov, A. S.; Korableva, S. L.; Semashko, V. V. (Turpion Ltd., 2016)
      Spectroscopic properties of Er : LiLuF4 and Er : LiYF4 crystals in the spectral region near 1.5 mm and the lasing characteristics of these crystals under in-band pumping at a wavelength of 1522 nm are studied. With the Er : LiLuF4 crystal, the maximum slope efficiency with respect to the absorbed pump power was 44 % at a wavelength of 1609 nm. Continuous-wave operation of an ...

    • Spectroscopy and femtosecond laser performance of Yb3+:YAlO3 crystal 

      Kisel, V. E.; Kurilchik, S. V.; Yasukevich, A. S.; Grigoriev, S. V.; Smirnova, S. A.; Kuleshov, N. V. (Optical Society of America, 2008)
      We report what we believe to be the first demonstration of cw and passively mode-locked Yb3+:YAlO3(Yb:YAP) laser operation under diode pumping. Spectroscopic properties of a 0.6 at.%Yb3+-doped YAP single crystal were investigated. Output power up to 1.2 W with slope efficiency of 64.5% in the cw regime and 225 fs pulse duration with average power of 0.8 W from a mode-locked Yb:YAP ...
