Low GDD ultrafast mirrors

Low GDD Ultrafast mirrors are designed for femtosecond applications to provide an optimized performance at certain wavelength and angle of incidence (AOI). This is achieved by careful selection of coating stacks to combine high reflectivity and low GDD value (from -10 fs2 to 10 fs2 at design bandwidth). Low GDD Ultrafast mirrors are intended for Ti:Sapphire, Nd:Glass, Er:Glass or Ytterbium doped host based lasers working in femtosecond regime. Read more

PCX PCV substrates

If an optical line has to withstand high energy density, reflecting elements are prefered over refractive optics. Reflecting focusing and defocusing optics are also perfect when dealing with ultrashort pulses. Concave and convex substrates can be coated with gold, silver or aluminum. Laser line or broadband dielectric coatings are also available. If necessary, latter coatings can feature optimized GDD values. Read more

Right angle prism mirror

Prism angular tolerance of 90 deg angle is in range of several arc minutes. Easy mounting does not required further alignment. Four standard metallic coatings are provided. The most common is aluminum coating which features a fair reflection in UV, visible and mid - IR wavelength ranges. "UV enhanced" aluminum coating is designed for UV applications. Protected silver coating is best suited for application in visible wavelength range, while protected gold is the most efficient coating over the entire IR range. Read more

High contrast thin film polarizers

High contrast Thin Film Polarizers (TFP) are made using advanced Ion Beam Sputtering (IBS) coating technology. UVFS dielectric coated high contrast thin film polarizers separate the s- and p-polarization components of high energy laser beams. Due to very low losses they are perfect for intra and extra cavity usage. Typical polarization ratio of these polarizers is well above 1000:1 (Tp:Ts). Read more
