摘要： A method and system for improved material processing using a laser beam. The method and system includes directing a laser beam above, at or below the surface of the material in one or more preferred patterns and with preferred laser pulse characteristics specific to the material to reduce or mitigate the accumulation or effects of gas, debris, fluid, or other by-products of photodisruption either at the location where additional laser pulses are being placed or in other sensitive locations in the material.

摘要： A closed-loop focusing system and method positions a focusing assembly to a desired positioned. A feedback positioning device, such as a linear encoder, provides an actual or “read” value for the linear movement of the focusing assembly. The desired position is compared to the actual position of the focusing assembly. If the two values are outside of a predetermined tolerance or valid range, then an audible or visual warning will be given. When a laser source is utilized with the focusing system, laser operation will be prevented if the two values are outside of an acceptable range. However, if the difference between the desired position and the actual position are within an acceptable range, the focusing assembly is repositioned to allow real-time systematic correction of the position of the focusing assembly.

摘要： Apparatus and methods of treating a hard lens region of an eye with a laser where one method includes identifying a boundary of the hard lens region, selecting a laser-parameter to enable a photodisruptive procedure in the hard lens region and to control a spreading of bubbles in the hard lens region, modifying a mechanical property of a posterior portion of the hard lens region in a proximity of the identified boundary by the photodisruptive procedure, and modifying a mechanical property of a portion anterior to the modified posterior portion of the hard lens region by the photodisruptive procedure. The laser bubbles can be applied to form incisions which are non transverse to an axis of the eye and intersect the lens fibers.

摘要： A method for creating an improved signal light is disclosed. For example, the improved signal light includes a housing, one or more first type of light emitting diodes (LEDs) emitting a light energy having a first dominant wavelength deployed in the housing, one or more second type of LEDs emitting a light energy having a second dominant wavelength deployed in the housing, a filter and a mixer. The filter may filter the light energy of the one or more second type of LEDs such that only a third dominant wavelength passes from the one or more second type of LEDs. The mixer may mix the light energy having the first dominant wavelength and the filtered light energy having the third dominant wavelength to form a light energy having a desired fourth dominant wavelength.
