A vertical external cavity surface emitting laser (VECSEL) is provided, in which the incident loss of a pumping beam is reduced. The VECSEL device comprising: a transparent substrate; an optical pump radiating a pumping beam onto a first surface of the transparent substrate; a first anti-reflection coating (ARC) layer formed of a first light-transmitting insulating material on a second surface of the transparent substrate to reduce loss of the pumping beam; a distributed Bragg reflector (DBR) layer formed on the first ARC layer; a periodic gain layer formed on the DBR layer; and an external cavity mirror facing the periodic gain layer.
