    • 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 ...

    • Diode-pumped passively Q-switched self-frequency-doubled ND:CNGS laser 

      Zhang, X.; Zhou, Y.; Yasukevich, A. S.; Loiko, P. A.; Mateos, X.; Xu, X.; Guo, S.; Wang, Z. (Optical Society of America, 2017)
      With Cr4+:YAG as a saturable absorber, a passively Q-switched self-frequencydoubled (SFD) laser based on a trigonal Nd:Ca3NbGa3Si2O14 (Nd:CNGS) silicate crystal was demonstrated for the first time. The maximum average output power at 532 nm was 16.2 mW, and the corresponding pulse repetition frequency, single pulse energy, pulse duration and peak power were 2.25 kHz, 7.2 μJ, 13.7 ...

    • Directed energy transfer due to orientational broadenning of energy levels in photosynthetic pigment solutions 

      Rubinov, A. N.; Zenkevich, E. I.; Nemkovich, N. A.; Tomin, V. I. (1982)
      The directed non-radiative energy transfer through monomeric molecules of chlorophyll “a” and pheophytin “a” at high concentrations (c ~ 10⁻²) in a rigid matrix of polyvinylbutyral has been found by using the nanosecond laser spectrofluorimeter. The phenomenon is caused by orientational broadening of pigment molecular spectra owing to its interaction with a solvent. The observed ...
