The demand for high-power lasers is growing and shows no signs of slowing down — but it takes a lot of effort to manufacture lasers that are not only high-power, but reliable. That was the key takeaway from Vancouver-based nLIGHT’s presentation at the annual Needham Growth Conference in New York City this week, where chief financial officer Ran Baraket gave attendees a quick assessment of the company’s financials and market position. The company was founded in 2000 and has grown by roughly 30 percent each year for the past four years, Baraket said, and has seen even stronger growth since going public in 2018.
