A diode-pumped 1.5µm waveguide laser mode-locked at 6.8GHz by a quantum dot SESAM
A diode-pumped 1.5µm waveguide laser mode-locked at 6.8GHz by a quantum dot SESAM
We report a passively mode-locked, diode-pumped waveguide laser operating in the 1.5µm spectral region using a quantum dot SESAM as the saturable absorber element. A repetition rate of up to 6.8GHz and an average power as high as 30mW is obtained during mode-locked operation. Minimum pulse duration of 2.5ps is produced at a wavelength of 1556nm. The repetition rate of the source was tuned by more than 1 MHz by changing the pump power, demonstrating a possible route towards integrated pulse repetition rate stabilisation.

Abstract
We report a passively mode-locked, diode-pumped waveguide laser operating in the 1.5µm spectral region using a quantum dot SESAM as the saturable absorber element. A repetition rate of up to 6.8GHz and an average power as high as 30mW is obtained during mode-locked operation. Minimum pulse duration of 2.5ps is produced at a wavelength of 1556nm. The repetition rate of the source was tuned by more than 1 MHz by changing the pump power, demonstrating a possible route towards integrated pulse repetition rate stabilisation.
