两光子晶体光纤激光器相干合成获得95.8W输出
Output Power of 95.8W from Coherent Combining of Two PCF Lasers
利用自成像腔技术实现了两PCF（光子晶体光纤）激光器的相位锁定，使两PCF激光器工作在同相模式，得到了高对比度的干涉图样，且在高功率输出状态下干涉图样保持稳定。在泵浦功率为150W和耦合输出镜的反射率为5%时，获得了95.8W的相干功率输出，相干功率合成效率为90.2%。实验表明耦合输出镜的反射率对相干输出功率有一定影响，当反射镜的反射率分别为5%，10%和15%时，两激光器同相模式输出的斜率效率分别为63.8%，61.6%和60.2%。
Phase locking of two PCF lasers is realized experimentally by using the self-imaging resonator technique. The two PCF lasers run in the in-phase mode and interference strips of high-contrast are observed even in high power operation. The coherent output power of 95.8W and the coherent power combination efficiency of 90.2% are obtained when the pump power is 150W and the reflectivity of coupling output mirror is 5%. Experiment shows that the reflectivity of coupling output mirror affects the coherent output power. The slope efficiencies of two fiber lasers running in in-phase mode are 63.8%, 61.6% and 60.2% for the reflectivity of 5%, 10% and 15%, respectively.
