As the submarine's speed increases, "silence" the emergence of the submarine, degaussing technology and non-magnetic hull materials used, all acoustic warfare weapons and equipment, so that the submarine hidden line and further enhance mobility. In addition, after the Cold War, with the task of the Navy's strategic shift from deep-sea confrontation in potentially hostile coastal waters to maintain military deployment, mine warfare and mine warfare defection would become more important. To counter the growing threat of submarine mine detection and solving problems, countries pay more attention to research a new Navy underwater target detection means such as blue-green laser underwater target detection. Back in the early 1960s, foreign submarine began to explore the feasibility of the laser probe. The working condition of laser pointer is good enough.Mark the object can be all kinds of metal materials and non-metallic. Such as stainless steel, aluminum, glass, plastics, ceramics, synthetic materials, wood, rubber, leather products, paper products, printed circuit boards, a variety of electrical and electronic components, cigarettes, buttons, detonators, metal parts, until the food packaging , pharmaceutical packaging, and even crabs. Number of units of its annual sales of about 4,000 to 5,000 units. It uses a laser from the light pumped Nd: YAG lasers, glass or metal CO2 laser cavity, in recent years, fiber lasers and solid-state lasers are mass producers into the marking, a complete set. Marking machine parts in a fixed position can also be marking items in the flight line on the marking. At the same time, people use high-energy electrons in the axial magnetic field in the millimeter-wave lateral movement maneuver, but until 1974 was the first time in the millimeter wave band to achieve stimulated emission. The worker is cleaning the storage area of finished laser pointer .For HP, since the position of the laser printer makes HP the current market interest should focus on expanding color laser printer applications, and guide the market demand, big color laser printer market and so on. Color laser printer with print speed, output quality is good, the effect is to maintain sustained, relatively high characteristic. Enter the market early, because of price barriers, limiting the market for color laser printer, color inkjet printer in many areas have been occupied. With the color laser printer product technology development, the decline in production costs, coupled with superior quality color laser printer, color laser printer market will continue to expand. For HP, how to find the most valuable user base, user base and understanding into the way the market bigger for HP color laser printer market, and quickly occupied the market is of great significance. Internationally renowned manufacturer of laser processing plant and some investment in China; some joint ventures with domestic production, have entered the general trend is the formation of international competition, domestic-oriented.
