System and method of photoaltering a region of an eye using an enhanced contrast between the iris and the pupil of the imaged eye. The system includes a laser assembly outputting a pulsed laser beam, a user interface displaying one of a first digital image of the eye and a second digital image of the eye, and a controller coupled to the laser assembly and the user interface. The first digital image has a first contrast between the pupil and the iris, and the second digital image has a second contrast between the pupil and the iris. The controller selectively increases the first contrast between the pupil and the iris to the second contrast between the pupil and the iris and directs the pulsed laser beam to the region of the eye based on one of the first and second digital images.

System and method of iris-pupil contrast enhancement

A plurality of jukeboxes each having a display, input component, audio output, and controller are connected over a network. The controller is configured to play music data sets selected by a user and to store local affinity data uploadable to the network. The controller is further configured to store network popularity and affinity data received from the network. The controller causes the display to present menus and screens based on the data received from the network. The controller is also configured to perform searches over multiple identification categories and store collections of music data sets based on multiple identification categories.

System and method of photoaltering a region of an eye using a high resolution digital image of the eye. The system includes a laser assembly for outputting a pulsed laser beam, an imaging system for capturing a real-time high resolution digital image of the eye and displaying the digital image of the eye, a user interface receiving at least one laser parameter input, and a controller coupled to the laser assembly, imaging system, and user interface. The controller directs the laser assembly to output the pulsed laser beam to the region of the eye based on the laser parameter input.

Ophthalmic laser apparatus, system, and method with high resolution imaging

An eye-surgical laser system includes a laser source, to generate a laser beam, an XY scanner, to scan a focal spot of a received laser beam in an XY direction essentially transverse to an optical axis of the laser system, and a lens group, disposed in the optical path between the laser source and the XY scanner, to receive the laser beam generated by the laser source, to precompensate an aberration of the laser beam, and to forward the precompensated laser beam to the XY scanner, the lens group having a movable lens, movable in a Z direction along an optical axis.

A technique for bandwidth control of an electric discharge laser. Line narrowing equipment is provided having at least one piezoelectric drive and a fast bandwidth detection means and a bandwidth control having a time response of less than about 1.0 millisecond. In a preferred embodiment wavelength tuning mirror is dithered at dither rates of more than 500 dithers per second within a very narrow range of pivot angles to cause a dither in nominal wavelength values to produce a desired effective bandwidth of series of laser pulses.

Bandwidth control technique for a laser

High power gas discharge laser with line narrowing unit

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 R 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 R tilt.
