Abstract

With the trend in portable electronics being continuously driven towards smaller and lighter products, the demand for laser-drilled microvias is increasing exponentially. With over 1,500 laser drilling tools currently being used within the printed circuit board industry, and a forecast of over 2,500 installed units before the end of 2001, Spectra- Physics has developed a high powered Q-switched Nd:YVO4 laser that can generate 12 watts of average power at 355nm. This power is generated with an optical-optical conversion efficiency of 11.5%(808nm to 355nm), which to our knowledge, is the highest reported to date for an end-pumped solid- state laser.
