Abstract
We present experimental results on a three-section master oscillator power ampli?er at 1.57 u?m to be applied in an integrated path di erential absorption LIDAR system for column-averaged atmospheric CO2 measurements. The application requires high power and good beam quality together with spectral purity and modulation capacity to be used in a random modulation CW LIDAR system. The device consists of a distributed feedback laser acting as master oscillator, a bent modulator section and a tapered optical ampli?er section with a tilted front facet to avoid coupled cavity e ects. The modulator section acts as an absorber or ampli?er when driven at zero or positive bias. Devices with di erent geometries and epitaxial structures were fabricated and characterized, presenting CW output powers higher than 350 mW and stable single mode emission. At the frequency required by the application (12.5 MHz) a high optical modulation amplitude and extinction ratio were achieved.
