  1. doi request reprint Enhanced 2D-image upconversion using solid-state lasers
    Christian 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...
  2. doi request reprint All passive synchronized Q-switching of a quasi-three-level and a four-level Nd:YAG laser
    Haynes 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...
  3. doi request reprint Theory for upconversion of incoherent images
    Jeppe 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...
  4. doi request reprint High-resolution two-dimensional image upconversion of incoherent light
    Jeppe 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...
  5. doi request reprint High-resolution mid-IR spectrometer based on frequency upconversion
    Qi Hu
    DTU Fotonik, Technical University of Denmark, Roskilde DK 4000, Denmark
    Opt Lett 37:5232-4. 2012
    ..We investigate water vapor emission lines from a butane burner and compare the measured results to model data. The presented method we suggest to be used for real-time monitoring of specific gas lines and reference signals...

    Haynes 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...
