Continuous-wave laser source at the 148 nm nuclear transition of Th-229
Vishal Lal, Maksim V. Okhapkin, Johannes Tiedau +3
A continuous-wave laser source at 148.4 nm based on second-harmonic generation in randomly quasi-phase matched strontium tetraborate, SrB4O7, is demonstrated. It provides (1.3-0.6+…

Nonlinear vibrational spectrometer for bioapplications featuring narrowband 1-m pulses and a recycled OPA pump beam
Zsuzsanna Heiner, Valentin Petrov, Mark Mero
Moving the detection wavelength in vibrational sum-frequency generation (VSFG) spectroscopy to the near-infrared (> 700 nm) can potentially enable the study of molecular interfaces…
