System for Figuring Thin Mirrors Using Ultrashort Laser Pulses
The inventors have developed an optical system, laser spot position determination process, and calibration process for deterministically figuring thin mirrors by creating stress inside the glass substrate (or other material transparent to the laser beam wavelength) using an ultrashort pulsed (USP) laser. This process is especially useful for low spatial...
