Abstract

Summary form only given. Using a 393 nm Nichia NLHV500 laser diode as a photodetector we present results demonstrating a strong two-photon response across a 200 nm range of visible wavelengths which enables sensitive measurement of intensity and interferometric second-order autocorrelations. The single-photon and two-photon response of the laser diode was found at several wavelengths. The modelocked sources were based on a 100 fs Ti:sapphire laser with a repetition rate of 85 MHz which synchronously pumped a periodically poled LiNbO/sub 3/ optical parametric oscillator (OPO).
