Abstract
An apparatus and a method for precisely wavelength-tuning single longitudinal mode tunable laser beams by utilizing a wedge prism are disclosed in which, instead of a tuning mirror, a prism is rotated, so that a single longitudinal mode can be maintained without causing a mode hopping of the longitudinal mode, thereby precisely tuning the wavelength. That is, a wedge prism 4 is inserted into the single longitudinal mode tunable laser resonator, and the prism is rotated, thereby precisely tuning the wavelength of the laser beams.
