Third-order-harmonic mode locking of a bulk erbium:ytterbium:glass laser at a 2.5-GHz repetition rate.
A bulk erbium:ytterbium:phosphate glass laser has been actively mode locked at the third-order harmonic by a bulk lithium niobate phase modulator. Light pulses of 9.6-ps duration, 2.5-GHz repetition rate, and 3-mW average power at 1530-nm wavelength have been obtained.
