Abstract
A frequency-doubled Nd:YAG laser was used to pump the RbTiOAsO4(RTA)/AgGaSe2 (AGSE) cascade optical parametric oscillator (OPO) to generate the 5.764 μm IR pulses, which correspond to the main absorption band of cholesterol. A maximum average output power of 40 mW was regularly obtained at 30 Hz and a pump power of 2.5 W with a long-term pulse-to-pulse fluctuation of ±10%.
