Tunable lasers are different if we compare with traditional lasers because they can continuously change their emission wavelength, color, in a given spectral range. As such, these quantum devices have found numerous applications in many diverse fields. Tunable lasers have played a crucial and sustained role in advancements of fundamental physics and science. Among basic fields that employ tunable lasers
