Dispersive coatings, including chirped mirrors and matched pairs

As part of our recently enlarged program for ultrafast laser applications, LASEROPTIK offers all kinds of dispersive coatings, including chirped mirrors and matched pairs. In addition, the use of high-quality substrates with superior roughness from our product lines Premium (< 2 Ȧ rms) and Super-polished (< 1 Ȧ rms) helps to achieve lowest losses for these critical components. A variety of standard sizes is available from stock.

For example, chirped mirrors compensate for the dispersion introduced by other elements like the laser crystal in a laser cavity. Or they serve as compressors in chirped pulse amplification systems (CPA). They include types like
