Single-Stage TOPTICA Isolators

Tunable Single Stage Performance

  • Designed and manufactured by the laser experts of TOPTICA
  • High power damage threshold (4 kW/cm2)
  • Highest guaranteed isolation in industry, high transmission
  • Center wavelength coverage encompasses 395 - 425 nm and 630 - 1400 nm
  • All internal components angled 1° to eliminate back reflection

TOPTICA’s product line of Faraday Optical Isolators are specially designed and manufactured in-house by the laser experts of TOPTICA to give industry leading performance in single stage configurations. Single stage devices provide at least 35 dB isolation and 85% transmission (> 43 dB and > 92% average) over individual wavelength ranges in total spanning 392.5 - 427.5 nm and 630-1400 nm.

All models are wavelength adjustable and can handle power densities up to 4 kW/cm2. These are the same components already used by TOPTICA in the industry-leading DL pro, TA-SHG pro, and TA-FHG pro laser systems. The same superior isolators that make TOPTICA lasers the industry standard are now offered individually. Custom and OEM isolator requests are welcome.
