Linearly polarized, single-frequency, widely tunable Er:Yb bulk laser at around 1550 nm wavelength

We report on a 36 nm tunable, single-frequency, linearly polarized Er:Yb:glass laser. A tuning range from 1528 to 1564 nm, with output power ranging from 1 to 8 mW, is achieved. Wavelength tuning and linearly polarized output are simultaneously obtained by using a special polarizing etalon with anisotropic absorption losses. (C) 1996 American Institute of Physics.
