SHORT PULSE LASER WITH ADJUSTABLE PULSE LENGTH
Embodiments of this invention relate to a system and method for performing laser ophthalmic surgery. The surgical laser system configured to deliver a laser pulse to a patient's eye comprises a laser engine that includes a compressor configured to compress laser light energy received, the compressor comprising a dispersion or spectrum altering component provided on a computer controlled stage connected to a computing device. A user providing an indication of a desired pulse width received by the computing device causes the computing device to reposition the stage and the component provided thereon, resulting in a different pulse length being transmitted by the laser engine.
1 . A surgical laser system configured to deliver a laser pulse to a patient's eye, comprising:
a laser engine, having
a compressor configured to compress laser light energy received, the compressor comprising a dispersion altering component provided on a computer controlled stage connected to a computing device;
wherein a user providing an indication of a desired pulse width received by the computing device causes the computing device to reposition the stage and the component provided thereon, resulting in a different pulse length being transmitted by the laser engine.
2 . A surgical laser system configured to deliver a laser pulse to a patient's eye, comprising:
a laser engine, having
a compressor configured to compress laser light energy received, the compressor comprising a spectrum altering component provided on a computer controlled stage connected to a computing device;
wherein a user providing an indication of a desired pulse width received by the computing device causes the computing device to reposition the stage and the component provided thereon, resulting in a different pulse length being transmitted by the laser engine.
3 . The surgical laser system of claim 1 wherein the laser pulse has a wavelength in the range of 300 nm to 3000 nm.
4 . The surgical laser system of claim 1 wherein the compressor further comprises a separate dispersion adjustment element configured to change the pulse width of the laser light energy.
5 . The surgical laser system of claim 1 wherein the compressor further comprises a separate dispersion adjustment element, the separate dispersion adjustment element configured to provide a fixed level of dispersion when positioned in a beam path of the laser pulse and no dispersion when removed from the beam path.
6 . The surgical laser system of claim 2 wherein the laser pulse has a wavelength in the range of 300 nm to 3000 nm.
7 . The surgical laser system of claim 2 wherein the compressor further comprises a separate dispersion adjustment element configured to change the pulse width of the laser light energy.
8 . The surgical laser system of claim 2 wherein the compressor further comprises a separate dispersion adjustment element, the separate dispersion adjustment element configured to provide a fixed level of dispersion when positioned in a beam path of the laser pulse and no dispersion when removed from the beam path.
