Abstract: An ophthalmic surgical system for monitoring incision performance includes a laser device, a camera, and a computer. laser device delivers a laser beam with a laser setting energy towards a target to create optical breakdowns in the target. The camera generates images of the optical breakdowns in the target. The computer instructs the laser device to create the optical breakdowns in the target to yield a test pattern. The test pattern comprises regions of optical breakdowns, where each region was created with a different laser setting energy. From the images, the computer identifies a lowest energy region with substantially continuous optical breakdowns, and designates the laser setting energy used to create the identified region as a threshold energy.

Abstract: A method for analyzing a laser system, which has a focused laser beam and a controllable deflection assembly for controlling the transverse and/or longitudinal position of the beam focus, said method comprising the steps of directing the laser beam or a partial beam branched therefrom downstream of the deflection assembly toward an optically nonlinear medium for the purpose of generating frequency multiplied radiation, the wavelength of which corresponds to an uneven higher harmonic of the wavelength of the laser beam, activating the deflection assembly, and measuring a power of the frequency multiplied radiation while the deflection assembly is activated. The conversion efficiency of the nonlinear process by which the frequency multiplied radiation is produced is dependent upon the focusability of the laser beam.
