Optical parametric oscillator

Abstract

The invention relates to an optical parametric oscillator (2) comprising: - a laser source system (10) generating a pump light beam (100), - a dichroic mirror (20) receiving the pump light beam and transmitting a first combination light beam (102), - a focusing optical system (30) receiving the first combination light beam, - a nonlinear medium (40), the nonlinear medium generating at its output a second combination light beam (104), - a focusing optical system (32) receiving the second combination light beam, - a dichroic mirror (22) receiving the second combination light beam, the dichroic mirror reflecting, in a first direction, the signal light beam (108), and - a hollow optical fiber (70) receiving the signal light beam, the hollow optical fiber being wound upon itself.
