Abstract

Wavelength conversion efficiency to the UV region is limited by a host of factors. To overcome several of these constraints, we use a fluxless-grown BBO crystal for fourth harmonic conversion of a linearly polarized Nd:YAG microchip laser, passively Q-switched with [110] cut Cr4+:YAG. The high quality BBO crystal used in the picosecond pulse width regime enables 60% conversion efficiency to give 3.4 MW peak power, 250 ps, 100 Hz pulses at 266 nm.
