$Measurement of refractive index using a Michelson interferometer$

Options Distributed Feedback Diode Lasers (DFB) Distributed Bragg Reflector Diode Lasers(DBR) Extended or External Cavity Diode Lasers (ECDL) (Expensive)
Distributed Feedback Diode Lasers • A diffraction grating is incorporated in the semiconductor lasing medium itself. • Narrow Linewidths • Not widely tunable though (6nm at best) • Operating Wavelength set during manufacturing. • Wavelength can be varied by strictly controlling the current and temperature parameters.
