High power gratings

Ibsen high power gratings can handle your power/energy

Fused silica transmission gratings from Ibsen offer an order of magnitude higher power handling capability than any other grating technology including conventional Au-coated reflection gratings and VPH gratings.

All our gratings are therefore ideal for high power applications.

Key benefits

  • Highest energy/power handling capability

  • High efficiency, broad bandwidth

  • High angle tolerance

  • Broad wavelength capabilities – from UV (<200 nm) to NIR (> 2000 nm)

  • Low wavefront distortion

  • Low stray light

Visible light spectrometers

Important applications

  • Femtosecond pulse stretching and compression for CPA (chirped pulse amplification)

  • Spectral beam combining

  • Pulse front tilting for terahertz generation

  • Beam splitting

  • Polarization splitting

Power damage threshold

The high power handling capability of our gratings has been third party tested – our gratings have proven capable of handling CW power density of >3 MW/cm2.

The high energy handling capability of our gratings has been reported by customers – our gratings have proven capable of handling peak power levels for femtosecond pulses of > 20 TW/cm2.

Further example power/energy uses of our gratings as reported by customers are given below.
