Disclosed is a laser oscillation device. According to the present invention, a second substrate is positioned in the upper part of a first substrate in such a manner that wedge cells are formed between the first and second substrates, and a liquid crystal layer is formed by two or more liquid crystals having different pitches which are injected into the wedge cells. The invention enables a consecutive wavelength-variable lasing process in a certain wavelength region.
