Fiber lasers show potential for use in high resolution laser spectroscopy. Tunable, single-longitudinal-mode operation has been achieved with fre.e-running laser linewidths of about 1 MHz. It would be straightforward to obtain much narrower linewidths using low frequency electronic fe.edback. In this paper I review this rapidly changing field and discuss the use of fiber lasers in spectroscopy.
