What is a tapered amplifier?
The tapered amplifier comprises an index-guided straight section and a gain-guided tapered section. Both facets are AR coated. The tapered amplifier can be seeded by a DFB, DBR or a RWL laser. Also an external cavity laser with a RWE laser can be used as a seed laser. The emission of these lasers can be amplified if the laser wavelength of the seed laser is within the gain profile of the tapered amplifier. Maximum output powers range from 0.5 to 2 W. The seed laser also called master laser is coupled into the narrow straight section. The amplified laser light is emitted at the facet of the tapered section. Because both sides have to be accessible, eagleyard provides the tapered amplifier with a C-mount package.
