Tunable Cateye Laser(CEL)
The MOGLabs cateye diode laser offers a new twist in external cavity diode lasers. A cateye reflector and ultranarrow filter replace the alignment-sensitive diffraction grating of conventional Littrow and Littman-Metcalf designs.
The CEL is robust, stable, and acoustically inert. You can literally hit it with a hammer and it will stay locked, and it is inherently self-aligning so you can tune tens of nanometres without having to realign. In combination with MOGLabs electronics, the linewidth can be well below 100 kHz. The CEL is available for most wavelengths between 450 to 530nm and 630 to 1620nm, at powers up to 250mW extra-cavity.
Enjoy the rock-solid stability normally expected only from DFB and DBR diodes – but with wide-range tunability, order-of-magnitude smaller linewidth, broader range of wavelengths, much lower sensitivity to optical feedback – and much lower diode cost.
