The satellite was manufactured by Hughes, 3 Satellite (TDRS-H, I, J) in a. The three satellites will be used to complement and enhance the existing TDRS system functions, and provide a wider bandwidth, FM is more flexible spatial data and image relay. Existing TDRS has provided nearly 20 years of communications services to the space shuttle and other spacecraft in orbit. TDRS will serve as the hub of the U.S. space communications. The second generation of TDRS satellites will have the dual capacity of data transmission and for the ground and in space to approximate a continuous communication link. This new satellite will increase the TDRS satellite series Ka-band communication capabilities. When Laser Pointer are the focus adjustable type.
High-power mid-infrared (3-5 Post) LD in the infrared countermeasures, infrared lighting, laser radar, atmospheric window 121, free empty Wen communication, atmospheric monitoring and chemical spectroscopy, etc. There are a wide range of applications. Green to ultraviolet vertical cavity surface emitting a wide range of applications in optoelectronics, such as ultra-high density 8 degrees, and optical storage. near-field optical scheme is considered to be an important means of high-density optical storage. vertical cavity surface emitting lasers can be used in full color The flat panel display, a large area of emission, the lighting, the light signal, light decoration, UV lithography, laser processing and medical aspects. The laser beam color of Laser Pointer will also decide the price. And because of the MBE, MOCVD technology achievements, so in 1978 the world's first semiconductor quantum well lasers (QWL) As heterojunction laser research and development, it greatly improve a variety of semiconductor lasers performance. Later, MOCVD, MBE growth technology matures, can grow high quality ultra-fine thin layer of material, after they successfully developed a more favorable performance of quantum well lasers, quantum well semiconductor lasers with double heterostructure (DH) laser, compared with a low threshold current, high output power, frequency response, narrow spectral line and temperature stability and high optical conversion efficiency of a number of advantages. The power of 50mW-100mW is enough for Laser Pointer .
From the late 1970s, semiconductor lasers significantly toward developing in two directions, one is based on the transmission of information for the purpose of information laser. The other is to enhance the power laser optical power for the purpose of in-pumped solid-state laser under the impetus of the application, high power semiconductor lasers (continuous output power in 100mw above, the pulse output power above 5W, can call it that high power semiconductor lasers) made a breakthrough in the 1990s, marked by the semiconductor a significant increase in the laser output power, the foreign-kilowatt high-power semiconductor lasers have been commercialized, the domestic sample device output has reached 600W.
