Why blue-sky thinking gives TOPTICA the power

摘要

The new blue mode laser from TOPTICA Photonics, Germany, is being billed as the first blue laser diode to combine high power output (50 mW) with a coherence length exceeding 25 m. The company reckons that its innovative design will finally offer a realistic alternative to gas-ion lasers for applications such as interferometry and holography in the blue-violet spectral range. "We have talked to OEM customers who have tried to use diode technology in the past, but got frustrated because of the low coherence," said Anselm Deninger, product manager at TOPTICA. "We will have a live system on show at the LASER exhibition, and we are excited to see how the laser will be received."
