The electronic atomizer device according to any one of claims 1-7, further comprising a heating target disposed in said housing and capable of absorbing said laser light source to generate heat; an atomizing cavity is formed in the shell, the heating target is at least partially arranged in the atomizing cavity, and airflow entering from the at least one air inlet hole reaches the atomizing cavity through the radiator.

15. The electronic atomization device of claim 14 wherein the surfaces of the heated targets have different absorbances.

16. The electronic atomizer device of claim 14, wherein the surfaces of said heated targets are formed with different temperature gradients.

17. The electronic atomization device of claim 14 further comprising a barrier disposed in the housing; the barrier is arranged between the heating target and the laser, and separates the laser from the atomizing cavity.

18. The electronic atomization device of claim 17 wherein the barrier is a light transmissive baffle or a light guide.
