Abstract
A laser video projector using an optical pumping valve is provided. The video projector according to the present invention forms an image using an optical pumping valve including a laser resonator for resonating light of a certain wavelength, an optical pumping source for performing pumping so that the laser resonator can generate a laser beam, and an optical valve for filtering the laser beam emitted from the laser resonator so that the filtered laser beam forms a picture instead of a cathode ray tube (CRT).
