Cavity dumper
Patent
·
OSTI ID:5641701
A laser cavity dumper capable of building up energy at a given mode or wavelength while emitting light of a different wavelength is created through use of a fox interferometer with an electrooptic cell. The fox interferometer can have either of two configurations. Placement of the electro-optic cell in either of two locations for each of these configurations will either cause the oscillating modes for the laser cavity to scan or undergo discreet shifts of preferred modes. The fox interferometer can be adjusted for zero output of a selected wavelength under normal operating conditions. A voltage change in the electro-optic cell then changes the resonance from the lossless state through the beam-splitter causing the cavity to dump. A new mode will begin to oscillate as the previous modes are depleted.
