In a recent blog posted on www.laserfocusworld.com, Strategies Unlimited analyst Allen Nogee noted that 2014 total laser sales are looking up, and some of the laggard areas are starting to correct themselves. His January 2014 market report forecasted worldwide laser revenue growth this year to be around 6%. And so far this seems to be right on track with what we're seeing. If this trend continues (always a big "if"), we will see the largest increase in annual laser revenue growth since 2011.
As baseball legend Yogi Berra once joked, "It's tough to make predictions, especially about the future." Yet leaving aside the specific revenue numbers, I confidently predict that 2014 will be another great year for laser technologies and applications—as this issue illustrates. For example, our cover story from Macquarie University shows how new quantum-integrated photonics devices can be direct-written in glass with a femtosecond laser (see page 25), and contributing editor Jeff Hecht writes about diode-pumped solid-state lasers now under test that can withstand the rigors of the battlefield (see page 29).
In addition, an article from Gigaphoton describes a new generation of UV excimer lasers for 450 mm semiconductor wafer manufacturing (see page 43), and a feature from Ophir-Spiricon describes how high-power fiber lasers can be characterized by imaging of Rayleigh scattering in air (see page 54). Finally, an article by colleagues at Worcester Polytechnic Institute and SmalTec International provides a means of precisely measuring machined stainless-steel surfaces with laser scanning confocal microscopy (see page 49).
To continue the baseball theme, the laser technologies and applications described in this issue are all home runs.
