ABSTRACT:
In a tuning arrangement for a semiconductor diode laser which includes, in a Littman arrangement, an external resonator, an optical collimator lens system and an optical refraction grid, a tuning arm is supported on a tuning table so as to be pivotable about a pivot axis and a resonator end mirror is mounted on the tuning arm and adjustment means are provided for adjusting the position of the tuning arm and of the distance of the end mirror surface plane from the pivot axis of the tuning arm and the refraction grid is supported so as to be pivotally and laterally adjustable for the adjustment of the distance between the grid surface plane and the pivot axis of the tuning arm to permit compensation of the chromatic dispersion of higher than the first order.
