| 20120113998 | MULTIBEAM COHERENT LASER DIODE SOURCE (EMBODIMENTS) - A multibeam coherent laser diode source comprises a master laser, a linear amplifier and two perpendicular amplifiers. The master laser and amplifiers are in the form of a single heterostructure containing an active layer, two limiting layers and a radiation influx area with an influx layer. The heterostructure is characterized by the ratio of the refractive index (n | 05-10-2012 |
| 20110150021 | DIODE LASER, INTEGRAL DIODE LASER, AND AN INTEGRAL SEMICONDUCTOR OPTICAL AMPLIFIER - Invention relates to three types of laser light sources: diode laser, integral diode laser (in form of integrally connected diode lasers) and integral semiconductor optical amplifier (in form of integrally connected driving laser diode and semiconductor amplifier element), which amplifier consists of original optical resonator of diode laser and original laser radiation coupling. Two reflectors in optical resonator of diode laser, which falls into three types of above-mentioned laser radiation sources, have greatest possible reflection factor on both sides thereof and radiation coupling from active layer is carried out, by-passing active layer, through broadband semiconductor layers of the modified heterostructure of diode laser with practically fully antireflective (less than 0.01%) optical face. Invention makes it possible to design superpower, high-performance, high-speed and reliable three types of sources of single-frequency, single-mode and multi-mode high quality laser radiation in broad wavelength band, to simplify the production and cut in production costs thereof. | 06-23-2011 |
