In the days when you can buy germanium diodes, capacitors and variable-headset from war surplus stores for pennies, your correspondent, as many of his contemporaries students build a solid-state version of his grandparents' crystal-set draw short wave radio broadcasts from around the world. Although such groups are only used to get, and therefore no need for a carefully crafted decline as a transmitter antenna, the biggest problem with them has always been build a highly effective dipole aerial. This usually consists of a length of 18-gauge insulated copper-clad steel wire tied loosely in the middle of a long pair of trees, although quite match your best antenna design based on a few miles sometimes barbed-wire around a pasture neighbor.

Blue laser modules offer a powerful and versatile tool for the medical and biomedical fields. Their unique properties, such as high precision, enhanced visibility, and selective interaction with biological tissues, make them invaluable for a variety of applications, including fluorescence microscopy, photodynamic therapy, ophthalmology, dermatology, dental procedures, and genetic research.

Sappire (as known as white sappire, molecular formula Al2O3) single crystal is an excellent multifunctional material. It has high temperature resistance, good thermal conductivity, high hardness, infrared transmission and good chemical stability. It is widely used in many fields of industry, national defense and scientific research (such as high-temperature infrared windows, etc.). At the same time, it is also a widely used single crystal substrate material, and it is the first choice for the blue, violet, and white light emitting diode (LED) and blue laser (LD) industries. And it is also an important superconducting film substrate. In addition to making Y-series, La-series and other high-temperature superconducting films, it can also be used to grow new practical MgB2 superconducting films.

Anamorphic prisms are utilized to rectify the asymmetric and elliptical beams generated by laser diodes, resulting in nearly circular beam shapes. By utilizing an anamorphic prism, the beam size can be altered along one axis while remaining unaltered along the other axis, allowing for expansion, reduction or reshaping of the beam.

Gallium nitride belongs to the third generation of semiconductor material with hexagonal wurtzite structure. It has the characteristics of large forbidden band width, high thermal conductivity, high temperature resistance, radiation resistance, acid and alkali resistance, high strength and high hardness. It has broad application potential and good market prospects in the fields of high-brightness blue, green, purple and white light diodes, blue and purple lasers, and anti-radiation, high-temperature and high-power microwave devices.
