Abstract

Summary form only given. We report measurements of these two dyes at wavelengths from 440 to 650 nm. The experimental light source is a singly resonant picosecond optical parametric oscillator (OPO) synchronously pumped by the third harmonic of a flash-lamp-pumped Nd:YAG laser. It is continuously tunable from 400 to 700 nm using two critically phase-matched BBO crystals mounted for walk-off compensation.
