Abstract:
An optical device, comprising:a laser source producing radiation of a first wavelength, wherein said laser source operates in a first short temporal mode, said first short temporal mode having a first pulse duration of between about 1 and 50 nanoseconds, and wherein said laser source operates in a second long temporal mode, said second long temporal mode having a second pulse duration between about 100 and 1000 microseconds;an optical switch, wherein an input to said optical switch is said radiation from said laser source, said optical switch directing said radiation from said laser source between at least a first optical path and a second optical path, wherein said laser source operates in said first short temporal mode when said radiation is directed to said first optical path, and wherein said laser source operates in said second long temporal mode when said radiation is directed to said second optical path;at least one non-linear crystal in said first optical path, said at least one non-linear crystal producing UV radiation; andan optical parametric oscillator cavity including a periodically polled non-linear crystal in said second optical path, said optical parametric oscillator cavity producing IR radiation.
