Active Coherence Stabilization
Jan 2012TOPTICA Photonics Inc.Request Info
Toptica Photonics Inc. has expanded its BlueMode diode laser family product portfolio to include GreenMode and RedMode. The new models deliver high power and high coherence from a single diode across the visible spectrum. All models are available with proprietary CHARM (coherence-advanced regulation mode) technology for active coherence control. The BlueMode devices, used in inspection and metrology tasks, combine high power (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 suitable for Raman spectroscopy and quantum cryptography, and red wavelengths are a common choice for interferometry.
