    Nanosecond sum-frequency generating optical parametric oscillator using simultaneous phase matching
    (Optical Society of American (OSA), 2005) Figen, Z.G.; Aytür O.
    We report a nanosecond sum-frequency generating optical parametric oscillator based on a single KTiOAsO4 crystal that is simultaneously phase matched for optical parametric generation and sum-frequency generation. Pumped at a wavelength of 1064 nm by a Q-switched Nd:YAG laser, this device produces 10.4-ns-long 8.3 mJ red pulses at a wavelength of 627 nm with 21% energy conversion efficiency. This device provides a simple and efficient method for converting high energy Nd:YAG lasers to a red wavelength. © 2005 Optical Society of America.

    Optical transitions of Tm3 + ions for amplifiers: how the local structure works in (1-x) TeO2 + (x) M (where M = LiCl, CdCl2, WO3) glass
    (OSA, 2002) Aydınlı, Atilla; Ay, Feridun; Sennaroǧlu, A.; Cenk, S.; Özen, G.
    Optical transitions of Tm3+ ions for amplifiers was presented. Stimulated emission cross-section at the peak wavelength of the emission bands was determined. It was concluded that Tm3+ doped binary tellurite glasses are promising materials for the infrared amplifiers.
