This dichroic mirror is placed directly after the 1030-343 nm THG crystal to reflect the generated 343 nm UV beam while transmitting the residual 515 nm and 1030 nm components. It enables compact, efficient separation of UV machining beams from their pump wavelengths. Non-Degrading coating ensures the laser source power doesn't drop over time.

This mirror can be used for Yb:YAG based ultrafast laser systems, such as:

  • “PHAROS” and “CARBIDE” by Light Conversion
  • “Monaco” series by Coherent
  • “FemtoBlade™” series by Lumentum
  • “TruMicro” series by TRUMPF
  • “IceFyre® FS” series by Spectra-Physics
  • “Satsuma” and “Tangor” series by Amplitude
  • “FemtoLux” series by EKSPLA
  • “FSL1030X2” by Thorlabs
  • “Jasper X1” by Fluence technology
  • “FS Series” by Photonics Industries

OPTOMAN’s Non-degrading mirrors engineered to deliver long-term optical performance, and higher LIDT in demanding laser applications. The technology directly translates into lower maintenance costs and reduced downtime, making it a smart, reliable choice for industrial, medical, and scientific UV laser systems.

These filters are optimized for reflecting 343 nm at a 45° angle of incidence, and transmit 515 nm and 1030 nm featuring an extended operational lifetime, even under continuous high average power or high repetition rate exposure.

With reflectance for III harmonic and transmittance for I and II harmonics, this filter is optimized for Yb:YAG based ultrafast laser systems.

Advantages of this product compared to other solutions in the market:

  • No color-change effect
  • Enhanced lifetime (over 10000h)
  • Higher LIDT (>0.35 J/cm² @ 343 nm, 300fs)

The technology directly translates into lower maintenance costs and reduced downtime.

 Products marked with this tag are SuperHero Tier products. They possess the best capabilities of OPTOMAN and make our R&D department proud.
