A RWE laser is a modified RW laser (see RW laser) for operation in an external cavity. Whereas the cavity of the RW laser is formed by the front and end facet of the laser chip the front facet of the RWE laser has an anti-reflecting (AR) coating. This enables the RW laser to be operated within an external cavity (see external cavity laser). An additional tuning element inside the external cavity allows the selection of the laser wavelength within the gain spectrum of the RWE laser.
