Electronics Letters, 2015•Wiley Online LibraryThe operation of an external‐cavity semiconductor diode laser with selectable coherence
and a tunable wavelength has been successfully demonstrated through the control of the
intracavity polarisation state. The laser has an intracavity half‐wave plate that is able to
rotate the orientation of the polarisation axis with regard to diffraction grating, where the
grating acts as a polarisation‐and wavelength‐selective element. As a result, it was possible
to continuously sweep the correlation widths from 230 kHz to 2.0 MHz by simply rotating the …
