Abstract
The present disclosure generally relates to surgical instruments for ophthalmic surgical procedures, and more specifically, surgical instruments that are capable of providing femtosecond laser pulses. In some aspects, a surgical instrument includes a body and a power amplifier disposed within the body. The power amplifier is configured to receive laser pulses from a laser source external to the body, and to deliver amplified laser pulses to an optical fiber extending toward a distal end of the body. The surgical instrument further includes an optical element disposed near the distal end. The optical element is configured to focus the amplified laser pulses.
Claims15
A surgical instrument comprising:
- a body;
- a power amplifier disposed within the body, the power amplifier configured to receive laser pulses from a laser source external to the body, and to deliver amplified laser pulses to an optical fiber extending toward a distal end of the body;
- and
- an optical element disposed near the distal end and optically coupled with the optical fiber, the optical element configured to focus the amplified laser pulses.
A system comprising:
- a surgical instrument comprising an optical element disposed near a distal end of the surgical instrument;
- and
- a chirped pulse amplification laser system comprising:
- a master oscillator disposed outside the surgical instrument;
- and
- a power amplifier disposed within the surgical instrument, wherein the power amplifier is optically coupled with the master oscillator and with the optical element.
