1. A laser irradiation device for performing treatment on human skin, comprising:
a casing that includes a grip part and a barrel part;
a laser oscillator that is accommodated in the casing and configured to generate a laser beam to be irradiated through the barrel part;
a contact sensor unit that includes electrodes exposed at an end of the barrel part and a contact sensing unit configured to sense an electric current flowing through the electrodes; and
a skin treatment unit that is detachably connected to the barrel part and is operated based on electric signals transmitted through the electrodes of the contact sensor unit.
