Transverse wave.

Explanation:

Lasers are electromagnetic waves. Electromagnetic wave is a result of oscillating electric field that induces oscillating magnetic field, which in turn produces oscillating electric field; the process repeats itself while the wave traveling at speed of light ( in vacuum).

The oscillating electric and magnetic fields are perpendicular to each other, yet both of them are perpendicular to the direction of probation. For example, if the wave is traveling to the right, the electric field is fluctuating up and down and magnetic field back and forth. Hence lasers are example of longitudinal wave.
