Abstract

In order to achieve laser pulses with microsecond duration in the green spectral range, we investigated the effect of overcoupled intracavity second harmonic generation with a Q-switched transversally diode pumped Nd:YLF laser. KTP and LBO crystals with different lengths were used to study the laser pulse energy, shape and duration at 526.5 nm. A pulse energy of 4.3 mJ was achieved with a FWHM pulse duration of 650 ns using a 5 mm long KTP and 3.4 mJ with 3.2 μs using a 10 mm long crystal. With a 10 mm long LBO a FWHM duration of 600 ns and with a 20 mm LBO 1.5 μs were generated both with a pulse energy of 4 mJ.
