The law of refraction is also called Snell’s law after the Dutch mathematician Willebrord Snell (1591–1626), who discovered it in 1621. Snell’s experiments showed that ... WebThe resonant cavity is defined by the highly reflective DBR mirror on one end, and a cleaved exit facet passivated and anti-reflectivity (AR) coated on the other end. The AR coated exit facet serves as the outcoupler for the diffraction-limited beam. Figure 2. Cross sectional diagram of DBR laser showing main features of the device.
