摘　　要：A compact low noise single frequency linearly polarized distributed Bragg reflector(DBR)fiber laser based on a 1.4-cm-long homemade Er^(3+)/Yb^(3+)-codoped phosphate single mode glass fiber has been demonstrated.An over 50 mW stable single frequency linearly polarized fiber laser was achieved.The measured slope efficiency is more than 21.6%,and the signal-to-noise ratio(SNR)is higher than 65 dB and the laser linewidth is less than 2.0 kHz.The laser RIN is measured to be less than-150 dB/Hz at the frequencies over 2.0 MHz,and the obtained linear polarization extinction ratio(LPER)is more than 30 dB.
