The diamond film is currently a hot topic

The purchase manager of laser pointer is about to go to Guangdong to purchase samples of laser pointer .
Currently, the U.S. has been able to synthesize two carat diamond, about 5 to 6mm size. However, harsh growing conditions, long period, its cost is also expensive than natural diamond. The diamond film is currently a hot topic. Artificial diamond films primarily use its mechanical properties, the optical and electrical properties is not yet well developed. In the electrical properties of diamond films of p-type doping has already achieved, according to the latest reports, the Japanese scientists through the incorporation of sulfur has the n-type doping of the diamond. This type of laser pointer has multiple functions so that it will be a bit more expensive.
Preparation of the intraocular lens is actually composed of crystals of the primitives (atoms, molecules or ions) dissociation after their portfolio. There are three categories in accordance with the crystal group decomposition different from the means of artificial Crystals. Solution method - the crystal raw material dissolved in the solution, specifically containing aqueous solution method, hydrothermal method and flux method. Aqueous solution crystal growth at atmospheric pressure and temperature is about eighty or ninety degrees Celsius; hydrothermal method at high temperature growth; flux rule is in the atmospheric pressure high temperature crystal growth. Melting - the crystal raw material melted completely, contains the Czochralski method, the crucible relative movement method, zone melting, the base, the cold crucible with the flame fusion method.
Flame fusion method, also known as the Verneuil method, invented in 1890 by French scientists Verneuil for the growth of artificial gems. The following figure shows the growth of flame fusion method the gem device schematic. Powder raw materials, feed hammer periodically beat hopper powder from the hopper gradually fall down, fall into the position 6, Entrance 4 and Entrance into hydrogen oxygen to form a hydrogen-oxygen flame, the powder melting . Melt fell into the seed crystal growth occurs, the seed to drop slowly, slowly growing crystal. Use this method to grow crystals of up to 1m. The price advantage of laser pointer also plays an important role. 
Produced by the piezoelectric crystal resonator used in the transmitters, has appeared in the First World War, is widely used during World War II, it created a new era of modern communications. The success of the single crystal silicon and integration technologies, the human into the swing of the modern computer age. Computer's processing speed faster and faster, and there will be a quantum computer, and photonic computer using the computer of a new computing approach, but the monocrystalline silicon, but no doubt a major contribution to the computer.
