Dual-wavelength optical parametric oscillator

摘要

Optical parametric oscillator (3) provides the light that the first ultrashort output pulse includes first wave length, and secondly ultrashort output pulse includes the light of second wave length, whereinAt least one first wave length and second wave length are individually controllable. The optical parametric oscillator (3) includes optical resonantor (10) comprising the first and second nonlinear optical elements (11,12) and including output coupler (13), input system (14) provides the first pump pulse nonlinear optical element pump pulse and first (11) and second (12) to the second nonlinear optical element, control system (15).
