Abstract

On this work we present a Titanium:Sapphire laser with simultaneous dual wavelength operation in the 890 nm region. Dual wavelength operation is obtained using a novel four stage birefringent filter in which we can control wavelength separation by tilting one of the filter elements. The laser operates in continuous wave pumped by a 5.5 Watts 532 nm source producing 100 mW at both wavelengths. We obtained wavelength operation with separation of 2.0 nm to 3.0, corresponding to frequency separation between 0.8 THz to 1.2 THz. The ultimate goal is the development of a source in the terahertz (THz) region of the electromagnetic spectrum for medical applications.
