14 GHz Operation of Q-Switched Diode Lasers

摘要

Q switched diode lasers have been operated in a continuous-inversion mode of Q-switching at pulse repetition rates of 14 GHz with a measurement system limited 40 ps FWHM pulsewidth. In continuous-inversion Q switching, the gain in the amplifier section of the device is continuously high while the laser is modulated by an intracavity electroabsorption modulator. The low-capacitance of the modulator section of a Q switched laser makes it attractive for high-speed modulation, especially when integrated with other electronic devices.
