摘要
The present invention is directed to a large area single-mode (LASM) laser system that provides a laser having a wider gain region and thus a higher power output without introducing the second transverse mode into the optical signal. The laser system of the present invention also reduces the laser junction temperature, thereby improving the reliability of the laser and of laser systems constructed therefrom. The present invention also provides a stabilized spectrum in an optical signal by providing a means for feeding back from an external fiber grating to the laser only a single mode and a selective spectrum of an optical signal generated by the laser.
