Wavelength combining with volume Bragg gratings in photo-thermo-refractive glasses
Abstract
Wavelength combining with a transmitting Volume Bragg Grating recorded in photo-thermo-refractive glasses is present. The combining condition is determined with theoretical simulation. The combining efficiency of 81.4% is obtained in the experiment, and it is influenced by the beam quality of the incident beam. The wavefront characteristics of combining beam are improved.
