摘要：
This invention is a broadband intra cavity laser mode convertor. This is a hologram of a complex phase mask imprinted inside of a volume Bragg grating with wide spectral width recorded in photo-thermo-refractive (PTR) glass. This hologram is a broadband phase converting monolithic device capable of use over a broad wavelength range at high instant and average power because of low absorption coefficient and low nonlinear refractive index of PTR glass. Therefore, it can be used for broadband optical beam transformations and conversion of modes in laser resonators.
