Abstract

We report on development of frequency-doubled diode-pumped ultrashort pulse Yb:KGW laser operating at 520 nm with approximately 200 fs long pulses at a repetition rate of 15 MHz. For ~2 W of absorbed pump power at 980 nm, the laser delivers up to 30 mW of average power at fundamental wavelength of 1040 nm, corresponding to a pulse energy of 2 nJ. The laser radiation was then frequency-doubled in a single pass configuration within a nonlinear BIBO crystal to produce femtosecond green radiation at 520 nm with peak power of ~200 W. The generated second harmonic served as excitation source of optical DNA sensor based on fluorescence lifetime measurements using the time correlated single photon counting (TCSPC) technique.
