US 12,403,039 B2 · Laser source for an ophthalmic surgical system

Abstract

A laser source for an ophthalmic surgical system includes a femtosecond seeder, an amplifier, a femtosecond pulse portion, a nanosecond pulse portion, and one or more switches. The femtosecond seeder generates femtosecond pulses. The amplifier amplifies laser pulses, which include the femtosecond pulses and nanosecond pulses. The amplifier amplifies the laser pulses by amplifying the femtosecond pulses and generating and amplifying the nanosecond pulses. The femtosecond pulse portion alters and outputs the femtosecond pulses, and the nanosecond pulse portion alters and outputs the nanosecond pulses. The switches receive the laser pulses from the amplifier, and direct the laser pulses to the femtosecond pulse portion or the nanosecond pulse portion. In other embodiments, the laser source includes a femtosecond seeder and a nanosecond seeder that generates the nanosecond pulses.
