2016 is not the best year for laser sales of materials for processing. While China in the brutal high power laser pointer market to achieve a fierce competition, and several Chinese laser manufacturers are out of the market.

Kiln-class materials processing lasers revenue grew 4% in 2016, but as most users who need fiber lasers already have these lasers, the trend towards fiber lasers instead of carbon dioxide lasers seems to have drastically slowed. Microfabrication processing lasers revenue grew 22% in 2016; in this area, almost all of the laser revenue growth came from two sub-applications: increased material processing and flat panel display manufacturing.

The revenue for lasers for increased material production, despite its rapid growth, is still relatively limited, accounting for only 4.5% of all microfabricated laser revenues. On the other hand, the construction of OLED display laser revenue in 2016 to achieve the explosion growth, accounting for almost one-third of the micro-material processing laser revenue. By contrast, in 2015, the application of laser revenue was less than half of 2016.

In addition, it should also be noted that Coherent (Coherent) is the only manufacturer of excimer lasers for this application, which is absolutely beneficial to the company. In January 2016, the company's share price was about $ 65 per share. As of December that year, the stock price of up to 137 US dollars per share, and in June 9, 2017, the stock has more than 249 US dollars per share.

What is the reason for the growth of the demand for excimer lasers, and how long will this demand trend last?

OLED industry executive director Barry Young explained that the growth of excimer 3000mw laser pointer demand and smart phones from the LCD screen to the OLED directly related to the change. As Apple uses OLED displays on its iPhone 8, coupled with the growing use of these OLED screens by many smartphone manufacturers, including many Chinese smartphone manufacturers, has caused this trend to a large extent.
