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 Ep jj c) and emits transform-limited pulses of >3.8-ps width and <5.6-pJ pulse energy (gain-switched mode locking) at 1602-nm wavelength (Es jj c). The relative change of the mode-locking frequency with the temperature is 3.65 3 1025y±C. The mode-locking acceptance bandwidth is 675 kHz near the axial-mode frequency spacing at approximately five times the threshold pump power.

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 Ep jj c) and emits transform-limited pulses of >3.8-ps width and <5.6-pJ pulse energy (gain-switched mode locking) at 1602-nm wavelength (Es jj c). The relative change of the mode-locking frequency with the temperature is 3.65 3 1025y±C. The mode-locking acceptance bandwidth is 675 kHz near the axial-mode frequency spacing at approximately five times the threshold pump power.| File | Dimensione | Formato | |
