(PhysOrg.com) -- One of the issues associated with lasers is their tunability. In many cases, if you want to produce a particular wavelength, you have to build a laser to accomplish this. In order to get another wavelength, you may have to build a different laser. A tunable laser would provide an opportunity to adjust the wavelength, without the use of another laser. One novel quantum cascade laser design that could achieve this is based on a dual upper state design.
