Patent ID: 8740890

Claim:
A system for ophthalmology or dermatology, comprising: a laser source unit having a fiber laser oscillator and amplifier for providing pulsed laser radiation having a pulse length in the femtosecond range, the laser source unit further including a pulse stretcher in optical communication with the fiber laser oscillator and amplifier, the pulse stretcher increasing the pulse length of the pulsed laser radiation to above 1 picosecond; a flexible light waveguide optically coupled at a first end to the laser source unit for receiving the pulsed laser radiation having a pulse length above 1 picosecond and guiding the pulsed laser radiation to a second end of the flexible light waveguide; and a hand piece coupled to the second end of the flexible light waveguide, the hand piece receiving the pulsed laser radiation from the flexible light waveguide and outputting a focused laser beam, wherein the hand piece includes: a transmission grating that compresses the pulse length of the received pulsed laser radiation to the femtosecond range; an electro-optical deflector in optical communication with the transmission grating, the electro-optical deflector functioning without moving parts to deflect the received pulsed laser radiation; and an f-theta objective in optical communication with the electro-optical deflector, the f-theta objective focusing the pulsed laser radiation deflected by the optical deflector onto a working plane.
