High Power Free-Space Optical Isolators
Single and Dual Stage Performance
Make every photon count
Highest transmission and extinction with TOPTICA isolators at all wavelengths.
TOPTICA isolators ensure stability of TOPTICA’s narrow linewidth, long coherence length lasers, and they can protect Watt-class lasers and amplifiers from damaging back reflections. TOPTICA can also offer custom form factors and wavelengths.
For more than twenty years, TOPTICA has offered narrow linewidth, single frequency, external cavity diode lasers. The spectrum and power of these lasers can be extremely sensitive to reflections from downstream optics, so it is critical that no light returns to the laser cavity. These stringent demands drove TOPTICA to develop its own line of single-stage (>35 dB) and double-stage (>60 dB) optical isolators.
