Solid-state laser for customized cornea ablation

摘要

A diode pump, solid state laser deep UV laser source is described for customized ablation in photo-refractive surgery. The solid-state deep UV laser source is tailored to have a pulse repetition rate of about 1 kHz and a relatively small spot size at both positions of the cornea and the scanner. Such a deep UV laser source enables the use of fast scanner and the implement of fast eye tracker. One embodiment of such a deep UV laser source comprises a passively Q-switched microchip laser, a diode-pumped multiple pass amplifier, and a wavelength converter.
