Karlsson G, Pasiskevicius V, Laurell F, Tellefsen J, Denker B, Galagan B, et al.
Appl Opt . 2008 Mar; 39(33):6188-92. PMID: 18354626
We report on passively Q-switched operation of a diode-pumped Er-Yb:glass laser with a Co(2+):MgAl(2)O(4) plate as a saturable absorber. Optical pulses with peak power exceeding 2 kW and a pulse...

Appl Opt . 2008 Feb; 37(30):7116-9. PMID: 18301535
Periodically poled flux-grown KTiOPO(4) was used for efficient extracavity 1064-nm Nd:YAG laser frequency doubling. A conversion efficiency exceeding 65% was obtained in Q-switched operation, and 1.34 W of average frequency-doubled...

Pasiskevicius V, Karlsson H, Tellefsen J, Laurell F, Butkus R, Piskarskas A, et al.
Opt Lett . 2007 Dec; 25(13):969-71. PMID: 18064243
Conical pumping was used in a periodically poled KTiOPO(4) optical parametric oscillator for singly resonant idler generation in a nearly diffraction-limited axial beam. A single signal-idler pair was generated over...
