Abstract
A laser being tunable in wavelength includes a first reflecting unit and a second reflecting unit, both reflecting units being arranged to at least partially reflect an incident beam of electromagnetic radiation towards each other, an optical path of said beam of electromagnetic radiation within said cavity, which is defined in length by said first and second reflecting unit, a dispersive device, which is arranged, such that a portion of said optical path of said beam of electromagnetic radiation traverses through said dispersive device, wherein said dispersive device comprises a dispersive characteristic representing a functional dependence of an optical path length of said portion with respect to wavelength of said electromagnetic radiation, wherein said optical path length increases with an increasing wavelength of said electromagnetic radiation.
