Request InfoCoherent Inc.The Mephisto family of single-frequency lasers from Coherent Inc. features linewidths of ~1 kHz over 100 ms, suitable for atom trapping and cooling, optical heterodyning, and injection locking and seeding. The lasers are based on nonplanar ring oscillator (NPRO) technology, which contains the entire intracavity beam path within a small neodymium-doped gain crystal that is resistant to contamination, easy to stabilize, and enables thermal and piezoelectric fine-frequency tuning. The compact system requires convective cooling, minimizing noise and maximizing frequency stability, and its...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 9/7/2023Fiber Laser Engraving MachineThe Monport GI Master Oscillator Power Amplifier (MOPA) fiber laser engraving machine from Monport Laser features a lightweight and portable design with a 90° rotating vertical arm.
