Abstract: The measurement of the frequency and intensity noise in a novel single-mode 2-μm Tm–Ho:KYF laser is presented. The laser frequency noise is measured by exploiting the
fringe side of the transmission of a Fabry–Pérot interferometer. The measured power spectral density of the frequency noise is principally characterized by a random-walk noise contribution, which sets an emission linewidth of ∼ 600 kHz for the 2-μm radiation. The relative intensity noise (RIN) reaches the quantum limit of −155 dB/Hz for Fourier frequencies above 1 MHz and shows a maximum level of −90 dB/Hz at the relaxation-oscillation frequency of 20 kHz.
