The dependence of the threshold of the CFC-NOPA cavity on the transmissivity of CBS for subharmonic optical field.
The traces (1) (2) and (3) are the calculated threshold pump power when γ1 is selected as 0.07, 0.05 and 0.03, respectively. The star is the experimentally measured result when γ1 = 0.05.
