哪十大屏幕显示?

我可是看好这中科院的“全固态激光器”，你说能用上么？

我认为，如果用在激光成相方面，光纤激光器倒时很有优势。
体积小，激光的模式好，功率又不大！

其实从原理上说，只要有功率相当的红、绿、蓝激光器，加上镀膜，
产生白激光或彩色激光倒不难？

只是光扫描系统似乎是个关键？
特别是要求大屏幕显示时，一般机械振镜的扫描速度怎么够呢？
或者先搞一个巴掌大小的玩玩？

IPG要把推广工作作好，就应该经常去走访用户，
然后拿出具体的案例，大家也可以了解更多一些实际使用情况，
相信大家也愿意听你的案例介绍呀？

可能你们把机器买出去就不管人家了吧？
还是用户也对你们技术保密？

如果要达到普通电视的图象效果，扫描系统的速度要达到多少才行？大屏幕显示似乎与速度无关，与扫描的角度有关。

那也可以沿用投影机的方法之一：液晶投影法，
只是不知道一般的液晶能否承受得了激光的照射，
而且这要把激光光斑放大，这对光斑的均匀性要求可不低？

土豆兄, 用了液晶何需再用激光?

大家好，我好长时间没有上来看帖子了。实际上，关于光纤激光和灯泵或ＬＤ泵YAG的比较等，大家讨论和争论的很多了。一个新技术或器件之所以被广泛关注，肯定是有其自身的高明之处的，但它不能也不会完全取代以有的技术（至少在相当长的时间内）。比如，灯泵的YAG，按说比光纤激光是落后多了，但在国际上的销售依然还非常火爆。YAG倍频出紫外有优势，但现在准分子激光还是不能替代。所以说，一个新技术有优势有潜力和应用前景，但现有的技术和器件能做好，也是非常关键和重要的。

Laser market to reach $3bn by 2008
8 January 2004

A US market analyst forecasts that the worldwide laser market will have a value of $3 billion by 2008.

The worldwide laser market will reach $3billion by 2008, according to a report by the US market analysts Business Communications Company (BCC).

The report, titled RGB-292 Solid State, Gas and Dye Lasers: Outlook for the Future, estimates that the value of the worldwide laser market in 2003 was just over $2 billion. Rising at an average annual growth rate (AAGR) of 9.1%, the firm expects the market to cross the $3 billion mark by 2008.

BCC divides its report into two sections: solid-state lasers and gas and dye lasers.

The firm predicts that the solid-state laser market will rise from $914.1 million in 2003 to $1471.4 million in 2008, an AAGR of 10%. Lamp-pumped lasers form the largest part of this sector and are predicted to grow at an AAGR of 8%, reaching $980.9 million by 2008.

In contrast, the market for diode-pumped solid state lasers is expected to grow with an AAGR of 14.8% to reach $490.5 million in 2008.

BCC says that Nd:YAG crystals, in either a flash-lamp-pumped or diode-pumped configuration, hold a 50% to 65% share of the solid-state market. Crystals such as Nd:YLF or Nd:YVO4 are said to hold a 10% share while the rest of the market is made up by other rare-earth or transition-metal-based systems.

Despite its greater value, BCC forecasts that the gas and dye laser market will have an AAGR of 8.4% between 2003 and 2008. Starting at a value of $1108.5 million in 2003, the company estimates the market’s value will rise to $1657.2 in 2008. The report claims that excimer lasers will show a high AAGR through 2008, fuelled by applications in basic research and industry.
