TUNABLE OPTICAL PARAMETRIC OSCILLATOR

A new principle for a tunable optical parametric oscillator (OPO) and a related method are disclosed. An OPO is tuned by setting the temperature of a non-linear element to select a desired signal/idler combination, and narrow-band operation is effected by tuning a birefringent filter in the OPO to a...

Zusammenfassung:	A new principle for a tunable optical parametric oscillator (OPO) and a related method are disclosed. An OPO is tuned by setting the temperature of a non-linear element to select a desired signal/idler combination, and narrow-band operation is effected by tuning a birefringent filter in the OPO to a temperature setting at which the filter matches the selected signal/idler combination, wherein broad and stable tunability is obtained by virtue of at least two different temperature settings of the non-linear element being matched to a single common temperature setting of the birefringent filter.
