Tunable Laser Technology
Generating Wavelengths from the UV Through the IR
Many types of lasers are designed to allow the operator to tune or change the output wavelength from the UV to the IR on demand. A tunable laser’s output wavelength can be varied over a wide spectral range, usually automatically under full computer control. Applications can be divided into two basic categories. First are situations requiring one or more discrete wavelengths not available from any single- or multiline fixed wavelength laser. Second, in some applications such as...
