Aerosol generating device with a laser

1. An aerosol generating device, the device comprising:

a target configured to receive vaporisable material;

a laser emitter configured to emit light to vaporise the vaporisable material received at the target;

a light guide for guiding light emitted from the laser to the target, the light guide extending from the laser emitter such that a portion of the light guide is received within the target; and

a reservoir for containing the vaporisable material, wherein the reservoir is removable from the aerosol generating device,

wherein the reservoir and the target are each at least partially formed as a hollow cylinder, whereby the reservoir at least partially surrounds the target.

2. The aerosol generating device according to claim 1 , wherein the target comprises fibres or yarn.

3. The aerosol generating device according to claim 1 , wherein a material of the target comprises ceramic and/or metal.

4. The aerosol generating device according to claim 1 , wherein the target comprises a first region and a second region, the first region having a lower density than the second region, whereby liquid is drawn from the first region to the second region via capillary action.

5. The aerosol generating device according to claim 4 , wherein each of the first region and the second region comprise fibres or yarn of the same material, the fibres or yarn being thicker in the first region than the second region.

6. The aerosol generating device according to claim 1 , wherein the laser emitter is configured to emit light in a wavelength spectrum matching an absorption peak of a surface material of the target.

7. The aerosol generating device according to claim 6 , wherein the laser emitter emits light in the infrared spectrum and the absorption peak of the surface material of the target is in the infrared spectrum.

8. The aerosol generating device according to claim 1 , wherein the device further comprises a perforable member located between the reservoir and the target which prevents liquid communication between the reservoir and the target until said member is pierced in use.

9. An aerosol generating system comprising the aerosol generating device of claim 1 , the system further comprising an outer shell for receiving the aerosol generating device.

10. The aerosol generating system according to claim 9 , wherein the aerosol generating device is configured to be at least partially insertable and removable from the outer shell.

11. The aerosol generating system according to claim 9 , wherein the laser emitter is configured to be received and held within the outer shell, the reservoir is configured to be received in abutment to the outer shell and the reservoir and the target are configured to be removable from the outer shell.

12. The aerosol generating system according to claim 9 , wherein the system further comprises control electronics that permits activation of the laser emitter once the aerosol generating device is received by the outer shell.

13. The aerosol generating system according to claim 9 , wherein the reservoir and the outer shell are rotatable relative to one another, whereby relative rotation of the reservoir with respect to the outer shell causes relative rotation between the light guide and the target.

14. A method of generating an aerosol with the aerosol generating device of claim 1 , the method comprising:

generating laser light with the laser emitter; and

directing the laser light to form an aerosol from the vaporisable material using the light guide for guiding light emitted from the laser to the target.
