here. Harvard news here.
We demonstrate monolithic and highly reflective mirrors that operate under high-power CW laser irradiation without damage.We measure reflectivities of greater than 98% and demonstrate damage-free operation using 10 kW of CW laser light at 1070 nm, focused to a spot of 750 μm diameter. In contrast, we observe damage to a conventional dielectric mirror when illuminated by the same beam. Congratulations!!! check the paper
