The present invention relates to an apparatus and a method for marking an object, particularly a vehicle, by disrupting the material of the interior or surface of the object. The system comprises a laser emitter (102), a laser beam delivery means (104) which can be flexible, and a marking heading (105) which is light enough to be carried by an operator. The laser marking system is very flexible in use, allowing many parts of objects, particularly vehicles, to be marked.

The invention claimed is: 1. A laser marking system for marking a part of a vehicle by disrupting the material of the interior or surface of the part of the vehicle, the system comprising: a marking head comprising means for directing a laser beam to define a pattern, a laser emitter, and laser beam delivery means for delivering the laser beam from the laser emitter to the marking head, wherein the marking head and laser emitter are movable and both configured to be carried by a person, and wherein the emitter is carried on a personal load carrying system which is rigidly mountable on a user's body, the marking head being mounted on a support arm which allows the marking head to be moved with respect to the personal load carrying system while transferring the weight of the marking head to the personal load carrying system. 2. A laser marking system according to claim 1, wherein the emitter and marking head are mounted on the support arm. 3. A laser marking system according to claim 1, wherein at least the marking head comprises a handle. 4. A laser marking system according to claim 1, wherein the laser beam delivery means permits the marking head to be displaced with respect to the laser emitter in at least two dimensions and preferably in at least three dimensions. 5. A laser marking system according to claim 4, wherein the laser beam delivery means permits the direction in which the marking head faces to be moved with respect to the laser emitter in two angular dimensions. 6. A laser marking system according to claim 1, wherein the laser emitter is a carbon dioxide laser. 7. The laser marking system according to claim 6, wherein the carbon dioxide laser is a pulsed carbon dioxide laser. 8. The laser marking system according to claim 7, wherein the carbon dioxide laser is pulsed by a Q-switch. 9. A laser marking system according to claim 1, wherein the weight of the marking head does not exceed 5 kg, being preferably less than 3 kg and preferably less than 2 kg. 10. A laser marking system according to claim 1, wherein the duty ratio of the laser beam is in the range 20-60%, preferably 30-50%, most preferably 35-45%. 11. A laser marking system according to claim 1, wherein the scanning speed of the laser beam across the object to be marked is in the range 2000-8000, preferably 3000-6000, most preferably 4000-5000 mm/s. 12. A laser marking system according to claim 1, wherein the power of the laser beam is in the range 5-20watts, more preferably 10-15 watts. 13. A method of marking a part of a vehicle by disrupting the material of the interior or surface of the part of the vehicle using a laser, comprising using the laser marking system of claim 1.
