Spectral Properties of an AlGaAs MOPA Laser Under Large Signal Modulation of the Oscillator or the Amplifier
In this paper, we report on the optical spectrum characteristics of a modulated, high power (> 1 W average), monolithic flared amplifier master oscillator power amplifier (MFA-MOPA) laser. The CW performance of this laser is presented in Reference 1. The master oscillator (MO) is a distributed Bragg reflector (DBR) laser operating in a single longitudinal mode under CW operation. The power amplifier (PA) is monolithically integrated with the MO and has a tapered gain region. The laser was capable of delivering over 1 W of CW power with the MO biased at 140 mA and the PA biased at 4.0 A at operating temperature of 15°C. The MFA-MOPA can be tuned with temperature at a rate of 0.07 nm/°C. The instantaneous CW linewidth of the laser was measured to be 300 MHz (0.74 pm).
