摘要
本文将行波半导体激光放大器（ＴＷ－ＳＬＡ）引入耦合腔锁模激光器中，详细分析了外腔的有效反射系数．结果表明：ＴＷ－ＳＬＡ的增益饱和及自相位调制对光脉冲具有调制特性，利用这类耦合腔激光器可实现自启动锁模以及具有获得超短光脉冲的可能性．
Abstract A travelling-Wave semiconductor laser amplifier(TW-SLA) is introduced in a coupled-cavity modelocking laser and the effective reflection coefficient of the external cavity is analyzed in detail. The results show that the TW-SLA can modulate the optical pulse due to its gain saturation and self-phase modulation (SPM). The self-starting modelocking can be achieved by such lasers and there would be the possibility to get shorter pulses.
