Abstract
A transmission type adaptive optical system that can be applied to a high power laser beam beyond a limit of deformable mirrors and corrects wavefront turbulence of a laser beam with adaptation to the wavefront turbulence is provided. By using a transmission type adaptive optical element of which a refractive index distribution changes based on temperature distribution thereof, a wavefront turbulence of a laser beam is corrected with adaptation to this wavefront turbulence. The wavefront turbulence is detected by a wavefront sensor and heating light in accordance with the detected wavefront turbulence is emitted to irradiate the transmission type adaptive optical element. The transmission type adaptive optical element transmits a laser beam as a target to correct a wavefront turbulence thereof and generates temperature distribution by the heating light and as a result generates the refractive index distribution.
