laser efficiency and photostability studies of dye solutions are done with Nd:YAG laser coupled to OPO system by transversely pumped at a repetition rate of 1 Hz. The exciting pulses are line focused onto the cell using a combination of positive and negative cylindrical lenses (f = 15 cm and f = -15 cm, respectively) perpendicularly arranged. The plane parallel oscillation cavity (2 cm length) consisted of a 90% reflectivity aluminum mirror acting as back reflector, and the lateral face of the cell acting as output coupler (4% reflectivity). The pump and output energies are detected by an Ophir powermeter. The photostability is evaluated by using a pumping energy and geometry exactly equal to that of the laser efficiency and it is monitored by the decrease in laser- induced fluorescence (LIF) intensity.
