The organic laser device

The invention is an organic laser apparatus including an organic compound that radiates laser light when current is injected. In an organic compound layer employed for the laser apparatus of the invention, a laminated structure and film thickness of each layer are determined in consideration of wavelength so as to radiate laser light. In the invention the organic compound layer collectively means each thin film containing mainly an organic compound formed between a pair of electrodes. The organic compound layer is formed so as to be sandwiched between a pair of electrodes and, preferably, formed by a plurality of layers each has a different carrier transport property and a different light emission wavelength. In addition, it is preferable to form to be a so-called resonator structure, in which a reflector is provided between the pair of electrodes.
