Abstract:
An ultraviolet laser apparatus comprising:(a) a first laser light generation source to generate first laser light and a first resonator resonating the first laser light, the first resonator defining a first optical path of the first laser light; and(b) a second laser light generation source to generate second laser light and a second resonator resonating the second laser light, the second resonator defining a second optical path of the second laser light; and(c) a nonlinear optical crystal;(d) whereby the first and second resonators are arranged such that a portion of the first optical path is substantially coincident with a portion of the second optical path and the nonlinear optical crystal is located along the substantially coincident optical path to provide an ultraviolet output laser light that is a sum frequency generation of the first and second laser lights.
