Optical Isolators

• High-performance optical isolation for laser systems
• Protects lasers from damaging back reflections and optical feedback
• Single-stage isolation of >35 dB
• Dual-stage isolation of >60 dB
• High transmission of >85% for single-stage and >80% for dual-stage models
• Wide wavelength coverage from UV to NIR
• Tunable wavelength designs for TOPTICA tunable diode lasers
• Compact mini isolators available for space-constrained systems
• Custom wavelengths and form factors available
• Rejection ports available for injection-locking applications
• Designed for integration with TOPTICA laser systems

Our high-performance optical isolators are designed with industry-leading performance to protect laser systems from damage and feedback. Perfectly suited for quantum technologies, designed for perfect integration into TOPTICA lasers.

Whether you need to enhance the stability of TOPTICA’s narrow-linewidth, long coherence length lasers or protect Watt-class lasers and amplifiers from damaging back reflections, trust in TOPTICA's reliable single-stage (>35 dB) and double-stage (>60 dB) optical isolators.

Designed and manufactured by the laser experts of TOPTICA
All wavelengths with the best performance, highest transmission & extinction from the UV to NIR, 360 nm to >1750 nm
All internal components are angled to eliminate back reflection.
Custom wavelengths and form factors available
The same high-quality isolators that make TOPTICA lasers the industry standard are now offered individually. Custom and private-label isolator inquiries are welcome.
