ABSTRACT:
A tunable laser source has a first laser source to generate a low power continuous wave laser light having a wavelength λ1. A second laser source generates a low power continuous wave laser light having a wavelength λ2. A pump laser source generates a high power pulsed laser light having a wavelength λ0. A first optical parametric amplifier (OPA) receives the laser light having a wavelength λ1and the laser light having a wavelength λ0and generates a high power pulsed laser light having a wavelength λ1. A second optical parametric amplifier (OPA) receives the laser light having a wavelength λ2and the laser light having a wavelength λ0to and generates a high power pulsed laser light having a wavelength λ2. A difference frequency generator (DFG), receives the high power pulsed laser light having a wavelength λ1and the high power pulsed laser light having a wavelength λ2and provides a high power pulsed laser light having a wavelength λ3wherein λ3=λ1*λ2/(λ2−λ1).
