When the CD-ROM or DVD recorders at the annual volume of more than 100 million units when the price is about $ 40. The price of the next generation of DVD recorders in 2006 is $ 390, nearly 10 times the target price. In order to reduce the price start from the most expensive parts. The laser head in the next-generation DVD manufacturing costs account for about 50%, one of the most expensive is a blue-violet semiconductor laser, accounting for about 30% of the cost of the laser head. In early 2007 on the price of the blue-violet semiconductor lasers, high power laser in the recorder about 5000 yen (about 315 yuan), low-power laser in the player is about 3000 yen (about 189 yuan ). Therefore, different top sellers of green beam laser is suitable for different customers.
To the standard configuration, the target price of high-power laser is roughly 500-600 yen (about 31-37 yuan). When DVD recorders year a volume of over 100 million units, the red semiconductor laser is this price. Laser manufacturers are increasing production capacity, there will be a large-scale production effect. Moreover, due to the improvement of manufacturing technology, and new manufacturers to introduce market price will be the rapid decline of the blue-violet semiconductor laser. Laser manufacturers now have 5 in 2008 will increase by 2-3, to meet the annual demand of 100 million units of production equipment was soon ready. 3000 - 4000 yen (about RMB 189-251 million) high-power lasers have been published. Areas and markets of  laser pen light will be formed and selected.
Low-power lasers seem to have signs of oversupply, the price fell below 1000 yen (about 63 yuan) has also been a large number of listed. 12 speed in 2009. On the performance of the equipment manufacturers in 2008 has reached to support dual-layer discs up to 8x write to the equipment manufacturer's target in 2009 is to support the limits of next-generation DVD storage haste --- 12X. Increasingly fierce competition between the laser into production manufacturers, the laser power has been greatly improved. For example, you can double-layer support off disk to achieve a 6x output power of 210mW blue-violet semiconductor laser, Sharp Corporation in May 2007, mass production and to ensure that the product component life of 10,000 hours. Recently, a kind of laser pen light becomes the favorite of the customers.
The sample price is set at ￥ 50,000 Sanyo also put into mass production for the same type of products. 240mW-class products support 8X, SONY Corporation, in 2007, began mass production. In addition, there are several manufacturers in 2009 to high-volume production of 300mW-class products that support 12X. The next-generation DVD applications in other areas. For next-generation DVD blue-violet semiconductor laser production technology continues to improve, not only can a large number of low-cost lasers, and GaN substrate production be increased in order to reduce costs and increase the diameter achieved progress, which will also affect other products. laser pen light is in famous in the oversea market for its high quality and performance.
If you can purchase cheap laser, is now actively developing the use of semiconductor lasers is possible to achieve a small projector as a light source. If the price declines of the GaN substrate may be applied to the GaN transistors. Matsushita Electric Industrial Company of the white LED, blue LED chip on the use of GaN substrates. Because of its high thermal conductivity, and the crystal defect density compared to the traditional products of the blue stone substrate 2 orders of magnitude lower. Light of the total radiation flux increased to 1.5 times. Easily collected enough to the GaN substrate, so this white LED. Faced with the decreasing trend of the blue-violet semiconductor lasers and LED prices. This top seller of laser pen light has the ordinary and commonly seen appearance.
