Femtosecond Laser Mirrors
OptoSigma Femtosecond Laser Mirrors, also known as Chirp Mirrors, or Dispersion Mirrors, have either low or negative Group Delay Dispersion (GDD) characteristics for use in chirp pulsed amplications systems (CPA), or a variety of applications for ultra short pulses of primarily Ti-Sapphire lasers. OptoSigma has three types, standard, wide band, and high power, in a varity of sizes. All utilize dielectric coatings on high precision glass substrates. Our Femtosecond mirrors are verified using a metrology device named, "Chromatis", manufactured by KM Labs in Boulder, CO. Custom sizes, wavelengths and pulse profiles available upon request.
