Active mode locking of an Er-diffusion-doped Ti:LiNbO{sub 3} waveguide laser by intracavity phase modulation to as high as the fourth harmonic (5.12 GHz) of the axial-mode frequency spacing is reported. The diode-pumped, pigtailed, and fully packaged laser with a monolithically integrated intracavity phase modulator has a threshold of 9 mW (incident pump power {ital E}{sub {ital p}}{vert_bar}{vert_bar}{ital c}) and emits transform-limited pulses of {ge}3.8-ps width and {le}5.6-pJ pulse energy (gain-switched mode locking) at 1602-nm wavelength ({ital E}{sub {ital s}}{vert_bar}{vert_bar}{ital c}). The relative change of the mode-locking frequency with the temperature is 3.65{times}10{sup {minus}5}/{degree}C. The mode-locking acceptance bandwidth is {plus_minus}75 kHz near the axial-mode frequency spacing at approximately five times the threshold pump power.
