Enhanced 2D-image upconversion using solid-state lasersChristian Pedersen
DTU Fotonik, Technical University of Denmark, DK 4000 Roskilde, Denmark
Opt Express 17:20885-90. 2009..The proposed technique can be further adapted for high efficiency mid-infrared image upconversion where direct and fast detection is difficult or impossible to perform with existing detector technologies...- All passive synchronized Q-switching of a quasi-three-level and a four-level Nd:YAG laserHaynes Pak Hay Cheng
DTU Fotonik, Technical University of Denmark, Frederiksborgvej 399, DK 4000, Roskilde, Denmark
Opt Express 18:23987-93. 2010..A minimum delay of 64 ns is observed between the two laser pulses, and by making the 946 nm pulse relatively long, a 79% temporal overlap is obtained when compared to the zero-delay scenario... - Theory for upconversion of incoherent imagesJeppe Seidelin Dam
DTU Fotonik, Department of Photonics Engineering, Technical University of Denmark, Roskilde, Denmark
Opt Express 20:1475-82. 2012..The fundamental differences between upconversion of coherent and incoherent images are investigated theoretically and experimentally. The theory includes the general case of upconversion using TEM(nm) modes... - High-resolution two-dimensional image upconversion of incoherent lightJeppe Seidelin Dam
DTU Fotonik, Technical University of Denmark, DK 4000 Roskilde, Denmark
Opt Lett 35:3796-8. 2010..A particular advantage of CCD cameras compared to state-of-the-art thermal cameras is the possibility to tailor and tune the spectral response leading to functional spectral imaging... 
Singly-resonant sum frequency generation of visible light in a semiconductor disk laserMartin Thalbitzer Andersen
DTU Physics, Department of Physics, Technical University of Denmark, 2800 Kgs Lyngby, Denmark
Opt Express 17:6010-7. 2009....- Experimental investigation of relative timing jitter in passively synchronized Q-switched lasersHaynes Pak Hay Cheng
DTU Fotonik, Technical University of Denmark, Roskilde, Denmark
Opt Lett 36:415-7. 2011..If the effect of the master laser's pulse-to-pulse jitter is removed, the residual timing jitter between the two lasers was 6 ns, which corresponds to the lower limit set by pump power fluctuations and noise from spontaneous emission...
