Abstract: 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.

Abstract: A two-step, diode-pumped solid-state laser is disclosed. A diode laser source pumps a first solid-state laser. The first solid-state laser in-turns pumps a second solid-state laser. The second solid-state laser contains all the parameters suitable for efficient deep UV generation. A direct application of the diode-pumped solid-state cascade laser is for deep UV generation for photo-refractive surgeries.
