We demonstrate a high power single-frequency fiber laser. By using phosphate glass fiber as its gain media, the laser can achieve high output power of 100 mW in centimeter-long linear cavity. Single-frequency single-polarization operation with <5 kHz linewidth and 65-dB signal-to-noise ratio (SNR) is realized by using external cavity polarization feedback technology.
