Assembly and method for performing surgical laser treatments of the eye

摘要

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.

1. 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, wherein the wavelength of the emitted pulsed treatment radiation is generated as a third harmonic of the basic wavelength and wherein a pulse repetition rate of the emitted pulsed treatment radiation is between about 100 kHz and about 100 MHz; wherein the wavelength of the emitted pulsed treatment radiation is between about 340 nm and about 350 nm; and wherein the basic wavelength is about 1040 nm.
