Patent attributes
A tunable diode laser system with external resonator in Littrow or Littman configuration has an optical lattice on which the light beam from a laser diode is diffracted, a support element to hold the lattice or to hold a mirror, which reflects the light diffracted by the lattice, and an actuator to change the position of the lattice or the mirror. The tunable diode laser system enables a reliable mode-hop-free tuning and furthermore is easy and economical to realize by having the support element include a carrier, on which the lattice or the mirror is arranged, and a base body, while the actuator acts on the carrier and rests against the base body. The carrier is connected to the base body via linkages, such that a linear deflection of the actuator is transformed into a rotation of the carrier in the plane of the light beam, while the center of rotation lies outside the base body.
