Active Coherence Stabilization
Feb 2012TOPTICA Photonics Inc.Request Info
Toptica Photonics Inc.’s BlueMode diode laser family now includes GreenMode and RedMode. The new models deliver high power and high coherence from a single diode across the visible spectrum. All models are now available with proprietary CHARM (coherence-advanced regulation mode) technology for active coherence control. The BlueMode devices, used for inspection and metrology tasks, offer up to 50 mW at 405 nm and single-frequency operation. The BlueMode wavelengths of 405, 445 and 488 nm are now complemented by the GreenMode (515 nm, 25 mW) and RedMode (638 nm, 30 mW; 685 nm, 25 mW) models. Blue/green wavelengths are suited for Raman spectroscopy and quantum cryptography, and red wavelengths are a common choice for interferometry.
