PURPOSE:To obtain the phototransistor by incorporating an induction absorbed light control element (LDSA) into a semiconductor laser, etc., controlling photon density by utilizing an optical pumping means and amplifying photons. CONSTITUTION:The LDSA (SA) is inserted into a solid laser (SE) such as a semiconductor laser, and the oscillation angle frequency of the LASER and the absorption angle frequency of the LDSA are equalized. When the photons of laser beams, etc. having hw angular frequency are projected, absorption is generated to a level (a) from a level (b). Electrons excited are supplied to the level (b) at all times by exciting electrons at a level (d) to a level (c) and spontaneously changing the electrons to the level (b) through the optical pumping means. The magnitude of the output-beam electric field of the phototransistor can be controlled by controlling the strength of the optical pumping of the LDSA, and the light change of the strength of the optical pumping of the LDSA is amplified and output beams are extracted as a large change. |
