美国的计算机工业在其35年的生存期间成长为有近400亿美元的年产值,而激光工业在其20年期间仅发展到有20亿美元。虽然看上去激光的数字是低了些,但实际上,它非常类似于计算机工业头20年的历程(见图1)。根据激光工业过去十年期间的增长 The U.S. computer industry grew nearly 40 billion U.S. dollars in its 35-year survival period, while the laser industry grew to only 2 billion U.S. dollars in 20 years. Although it looks like the number of lasers is lower, in fact it is very similar to the first 20 years of the computer industry (see Figure 1). According to the laser industry over the past decade of growth
