The intracavity design of the OPO utilizes the high circulating power in the cavity to achieve extremely low threshold pump power. 4 series with 3 wavelength cover ranges are provided upon request.
OPO-B and OPO-S are the OPO module with fixed wavelength specified by the customer in the range of either α, β or γ. In contrast, OPO-TB and OPO-TS are the wavelength tunable OPO that cover the entire range.
B: broad bandwidth (few nm)
S: single longitudinal mode
e.g. OPO-TS: tunable, single longitudinal mode
