We propose a 170 GHz corrugated diamond window (CDW), which can provide 1-2 MW CW power transmission in broadband reflectionless regime for the window as a whole, as well as for each of the diamond surfaces, since the corrugations work like the well-known quarter-wave matching coatings used for optical windows. This design allows for arbitrary window thickness, which is beneficial for thermal stress management. The corrugation will be produced on diamond surface by means of femtosecond laser ablation using protocols developed at Euclid over the years.
