Laser Diode Based Spectrometer Using Fiber Gratings (GSC-13915)
In spectroscopic applications, the light source wavelength, tuning range, and spectral quality are important. High performance systems that use tunable dye or Ti: sapphire lasers are bulky, inefficient, and expensive. Commercial laser diode systems are available, but they are still reasonably expensive (over $5,000) and too large for many applications. Compact laser diode spectrometers using Distributed Bragg Reflectors (DBR) and Distributed Feedback (DFB) gratings are also available, but the wavelength selection is limited.
