[...] in order to get high values, one has to have either high energy per pulse, short pulse length or small spot sizes. Since small spot sizes are a function of wavelength, UV lasers can produce high peak powers - especially as most UV lasers also have a short pulse length relative to infrared lasers. [...] a 2OW CO2 laser will cost about US$250/W to purchase, a 2OW fibre laser will cost about US$600/W, a 2OW, 355nm DPSS laser will cost about US$8,000/W and a 2OW, 1 0ps pulse length fundamental wavelength laser will cost about US$15,000/W. [...] UV and short pulse lasers are best used where edge quality and precision considerations outweigh cost considerations.
