Abstract
We have developed a 50 W all-fiber, single-frequency, low-noise master oscillator power amplifier laser operating at 1013 nm, with an efficiency of 67%. The output signal shows an optical signal-to-noise ratio of 50 dB and excellent noise properties. These are to date and to the best of our knowledge, the highest reported figures of merit for a single-frequency laser at this wavelength. The relative intensity noise of the laser is analyzed and discussed.
