Description

The current use of the laser crystal has been the beginning of the development of several substrate materials to the current number of 10 species, but the range of applications, the main or “three basic laser crystal,” They are neodymium-doped yttrium aluminum garnet ( Nd: YAG), neodymium-doped yttrium alum acid (Nd: YVO4) and titanium-doped gem (Ti: Al2O3) crystals. Among them, high-power laser applications is mainly Nd: YAG, a small low-power laser applications is mainly Nd: YVO4, its appearance marks the era of solid-state lasers, Ti: Al2O3 crystals can be harmonized in the main, the application of ultrafast laser. The technology improvement of    green laser pointer will be recorded in the report.
Nd: YAG Laser Rod. Neodymium-doped yttrium aluminum garnet (Nd: YAG) is still the best overall performance of solid-state laser materials with high mechanical strength, optical properties of uniformity, higher thermal conductivity advantages. Because Nd: YAG crystal of these advantages, it has been widely used in military, medical and other fields, as the current use of solid-state laser materials, the largest laser crystal, laser crystal and occupied the position of chief of 40 years. On the military side, Nd: YAG crystal as the most common solid-state lasers work material, solid-state laser technology has become the backbone of the military, more than 90% of the current solid-state lasers for military Nd: YAG crystal as the working substance. The quality feedback of    100mW green laser pointer will be discussed during the meeting.
In the field of medicine and health care, Nd: YAG laser has also been a large number of medical device applications. In industry, the Nd: YAG crystal for high power laser output can be widely used in material processing, for example, Nd: YAG laser processing of auto parts has been the world’s many car manufacturers use. Yb: YAG crystal is an excellent diode-pumped solid-state laser material with high doping concentration, high quantum efficiency, long fluorescence lifetime, absorption bandwidth and other characteristics. In theory, Yb: YAG laser can be used as laser weapons, small, efficient laser source. With the development of InGaAs laser diodes, Yb: YAG crystal with low thermal efficiency, and the advantage of being suitable for LD pumping new understanding. The company will perform more inspection of    green laser pointer      .
At present, the increase of LD-pumped Yb: YAG solid-state laser research into the development of high-power, integrated and miniaturized solid-state lasers as a major direction, more and more attention. Laser crystal materials chain laser crystal materials are laser industry sub-sectors, upstream related to rare earth mining, smelting and related chemical industry, directly downstream processing industry is the production of lasers, laser applications and industries including military, medical processing, optical communications, laser measurements. Better laser industry, several major countries / regions and market development. Some technical problems have been put forward during the final acceptance of    50mW blue violet laser pointer.
The global laser market conditions and trends 2004-2009 Figure 2 shows the global laser market income. From 2004 to 2008, global commercial laser rapid income growth, average annual growth of nearly 7.5% from 2004 sales of $ 5.38 billion in 2008 rose to 70.1 billion U.S. dollars, but by 2008 the global financial crisis, the global laser rapid decline in market income 2008-2009 fell 24.1%, total revenue fell to 2003 levels. However, as the world’s major producing countries adopted a series of measures to promote economic development, making the national economy gradually recovered, the next few years, laser market will remain close to 6% annual growth. The maintenance of    200mW green Laser Pointer is very easy to carry out.
