Abstract :
UV power of 50.3 nW is obtained using two microlensed diode lasers in a single pass geometry, through sum-frequency mixing in a non-linear BBO crystal. The 413 nm microlensed diode laser is used in external cavity and the 662 nm microlensed diode laser as a free running source. The narrow linewidth and broad tuning range create a tool readily compliant with the stringent requirements of laser spectroscopy.
