Abstract
We report on the development and comprehensive characterization of a room-temperature single-mode 2-μm Tm-Ho:KYF laser. A maximum CW output power of ∼70 mW at the central wavelength of 2.078 μm has been obtained. Using a 5-mm long intracavity birefringent filter the single-mode emission wavelength can be tuned over a range of ∼40 nm. Both frequency and relative intensity noise have been investigated showing a 1-ms emission linewidth of ∼600 kHz and an intensity noise spectrum that is quantum-noise limited for Fourier frequencies higher than 1 MHz.
