need help. Laser triggered switch for small electric motor. Answered

Hey I've been thinking of making a simple circuit connected to my window which is operated by turning a small handle. The aim of this project is to be able to activate the motor via a typical laser beam from outside the building to activate the motor, thus opening the window. Can someone help me draft up the schematics for this, or provide input as to how I would go about achieving this? Any help is much appreciated.
