Laser light source and LIDAR system comprising the laser light source

A LIDAR system comprising:

• a laser light source;
• wherein the laser light source comprises:
• an edge-emitting first semiconductor laser adapted to emit a first radiation of a single optical mode;
• an array of surface-emitting semiconductor lasers;
• a first voltage source wherein a voltage below a threshold voltage of the surface-emitting semiconductor lasers is configured to be applied to the array of surface-emitting semiconductor lasers,
• wherein the edge-emitting first semiconductor laser is configured to excite the array of surface-emitting semiconductor lasers beyond threshold, the array of surface-emitting semiconductor lasers is adapted to absorb the first radiation and to emit laser radiation at an emission wavelength through an injection-locking mechanism,
• wherein the wavelength of the first radiation and the emission wavelength are configured to be modulated by changing a current intensity in the edge-emitting first semiconductor laser;
• and
• a second voltage source, wherein a variable voltage is configured to be applied to the edge-emitting first semiconductor laser, so that the current intensity configured to be impressed in the edge-emitting first semiconductor laser is configured to vary.
