Abstract

Active mode locking of an Er-diffusion-doped Ti:LiNbO3 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 Epc) and emits transform-limited pulses of ≥3.8-ps width and ≤5.6-pJ pulse energy (gain-switched mode locking) at 1602-nm wavelength (Esc). The relative change of the mode-locking frequency with the temperature is 3.65 × 10−5/°C. The mode-locking acceptance bandwidth is ±75 kHz near the axial-mode frequency spacing at approximately five times the threshold pump power.
