Abstract
An arrangement for carrying out surgical laser treatments of the eye is adapted to emit pulsed treatment radiation with a wavelength of between about 190 nm and about 380 nm and a pulse duration in the femtosecond range. Such treatment radiation allows nonaggressive corneal or intraocular laser treatment of the eye, for example in order to make corneal cuts or deliberately ablate corneal tissue.
Claims20
An arrangement for carrying out surgical laser treatments of the eye, the arrangement comprising:
- a laser source configured to emit pulsed treatment radiation with a wavelength between about 340 nm and about 360 nm and a pulse duration in a range between an attosecond range and a picosecond range, wherein the emitted pulsed treatment radiation wavelength is generated from a basic wavelength of between about 1020 nm and about 1084 nm and wherein a pulse repetition rate of the emitted pulsed treatment radiation between about 100 kHz and about 100 MHz.
A method for carrying out a surgical laser treatment of an eye, the method comprising:
- emitting pulsed treatment radiation with a wavelength between about 340 nm and about 360 nm and a pulse duration in a range between an attosecond range and a picosecond range, wherein the emitted pulsed treatment radiation wavelength is generated from a basic wavelength of between about 1020 nm and about 1084 nm and wherein a pulse repetition rate of the emitted pulsed treatment radiation between about 100 kHz and about 100 MHz.
A system for laser treatment of the eye, the system comprising:
- a laser source adapted to emit a radiation having a basic wavelength between about 1020 nm and about 1084 nm;
- a frequency converter for converting the radiation to a treatment pulse with a wavelength between about 340 nm and about 360 nm;
- and
- a controller for controlling the treatment pulse to a duration in a range from about 1 picosecond to about 1 attosecond and for controlling a pulse repetition rate of the treatment pulse to be about 100 kHz and about 100 MHz.
