SMART LASER WITH FAST DEFORMABLE GRATING

摘要

A smart laser having automatic computer control of pulse energy, wavelength and bandwidth using feedback signals from a wavemeter. Pulse energy is controlled by controlling discharge voltage, wavelength by controlling the position of an RMAX mirror and bandwidth is controller by adjusting the curvature of a grating to shapes more complicated than simple convex or simple concave. A preferred embodiment provides seven piezoelectric driven pressure-tension locations on the back side of the grating at 5 horizontal locations to produce shapes such as S shapes, W shapes and twisted shapes. Preferred embodiments include automatic feedback control of horizontal and vertical beam profile by automatic adjustment of a prism plate on which beam expander prisms are located and automatic adjustment of the RMAX tilt.
