    Abstract: An optical parameter oscillator system is proposed for use in a continuous wave pump laser system having a single-frequency pump source. The system comprises a single-resonance resonator having a nonlinear medium to produce a first and second parametrically generated wave in response to the pump wave from the single-frequency pump source. The system includes means for controlling the cavity length of the resonator, means for controlling the pump frequency of the pump source and means for controlling the temperature of the nonlinear medium. The system provides for a reliable singly-resonant optical parametric oscillator capable of emitting laser light with high spectral purity and frequency stability over a wide spectral range and is resistant to mode hopping.

    Abstract: A method for forming a patterned film on a substrate, the method including: providing a first flowable medium on the substrate and a second flowable medium on the first flowable medium, the first and second flowable media having different dielectric properties and defining an interface there between; applying an electric field to the interface for a time sufficient to produce a structure in the first flowable medium along the interface; and hardening the structure in the first flowable medium to form the patterned film.
