Osram Opto Semiconductors (www.osram-os.com) has developed an optical pumped semiconductor (OPS) disk laser prototype that puts out 8W of 980-nm optical power from 19W of pumping power. This is an order of magnitude more efficient than previous semiconductor lasers. One key to success is highly effective heat dissipation of excess energy from the laser's active area. Osram sees this as a major breakthrough toward consumer uses such as laser television displays.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
