1. A laser source for an ophthalmic surgical system, the laser source comprising:
a femtosecond seeder configured to generate a plurality of femtosecond pulses; and
an amplifier configured to:
generate a plurality of nanosecond pulses; and
amplify a plurality of laser pulses, the plurality of laser pulses comprising the plurality of femtosecond pulses and the plurality of nanosecond pulses, the amplifier configured to amplify the plurality of laser pulses by:
amplifying the plurality of femtosecond pulses generated by the femtosecond seeder; and
amplifying the plurality of nanosecond pulses generated by the amplifier;
a femtosecond pulse portion configured to alter and output the plurality of femtosecond pulses;
a nanosecond pulse portion configured to alter and output the plurality of nanosecond pulses; and
one or more switches configured to:
receive the plurality of laser pulses from the amplifier; and
direct the plurality of laser pulses to the femtosecond pulse portion or the nanosecond pulse portion.
