摘要：
The damage threshold of femtosecond laser mirrors is critical in the construction of femtosecond laser systems. Therefore, we developed a uniform and efficient test method for femtosecond mirrors for the most relevant laser wavelengths of 266 nm,400 nm, 800 nm and 1030 nm and tested various broadband metal and metal-dielectric hybrid mirrors. With this, damage threshold values as high as 1 J/cm(2) were observed for laser pulses with pulse lengths between 70 and 90 fs.
