We have produced bright tunable squeezed light by second-harmonic gene
ration in a singly resonant cavity. We have investigated the effect of
input coupling and fundamental power on the squeezing. Up to 400 mW o
f continuous-wave mode-locked tunable squeezed light was produced at w
avelengths as short as 389 nm, and more than 1.5 dB of squeezing was i
nferred. (C) 1997 Optical Society of America.
