Publikováno v: Quantum Electronics. 51:196-200
We report an analysis of attained output powers of laser diode bars (LDBs) and power densities of two-dimensional laser diode arrays (LDAs). A new LDA design is proposed and its thermal regime is simulated. The cw output power of the proposed LDA con

Dual-wavelength generation at the transverse mode locking in a diode-end-pumped passively Q-switched Nd:YLF/Cr4+:YAG laser
Autor: V V Bezotosnyi, Mikhail V Gorbunkov, A. L. Koromyslov, V F Pevtsov, E. A. Cheshev, Yu. M. Popov, V. G. Tunkin
Publikováno v: Bulletin of the Lebedev Physics Institute. 44:1-4
A dual-wavelength generation at 1047 and 1053 nm is implemented in a diode-endpumped Nd:YLF laser Q-switched by Cr:YAG. This generation is obtained by the tuning of the cavity length near the regions of the transverse-mode degeneracy.
