Abstract
A fiber-coupled tunable Er-Yb:glass minilaser is presented with output power of 40 mW. The laser can be stepwise tuned in single-frequency operation from 1530 to 1560 nm by compressing a fiber Bragg grating that provides selective feedback. Constant output power (fluctuation < 0.8 dB) over the full tuning range is demonstrated. The relative intensity noise spectrum was measured to be <150 dB/Hz for frequencies >2 MHz.
