TL;DR: In this paper, a self-imaging unstable positive branch resonator configurations including GRMMA have been tested with flashlamp-pumped Nd:glass rod lasers.
Journal ArticleDOI
Crystal growth, spectroscopy and first laser operation of a novel disordered tetragonal Tm:Na2La4(WO4)7 tungstate crystal

TL;DR: Tm3+:Na2La4(WO4)7, a disordered tetragonal scheelite-type tungstate crystal, is grown by the Czochralski method.
Journal ArticleDOI
Comparative study of Yb:KYW planar waveguide lasers Q-switched by direct- and evanescent-field interaction with carbon nanotubes.

TL;DR: From the calculation of the configuration-dependent stability range, the beam size and the electric field distribution in the Yb:KYW planar waveguide, it is confirmed that the evanescent- field interaction scheme makes stable Q-switching possible with much lower intensities at saturable absorber compared to the direct-field interaction scheme in the presented waveguide laser operation.

Tm:CaGdAlO4: spectroscopy, microchip laser and passive Q-switching by carbon nanostructures
Pavel Loiko,Xavier Mateos,Sun Young Choi,Fabian Rotermund,Christoph Liebald,Mark Peltz,Sophie Vernay,Daniel Rytz,Yicheng Wang,M. Kemnitzer,Antonio Agnesi,Elena Vilejshikova,Konstantin Yumashev,Uwe Griebner,Valentin Petrov +14 more
TL;DR: In this paper, a single-walled carbon nanotubes (CVD-grown graphene and randomly-oriented arc-discharge singlewalled single-nodes (SWCNTs) in a PMMA film were used for passive Q-switching of the Tm:CaGdAlO4 laser-saturable absorbers.
