Newport's ultrafast broadband turning mirrors reflect over 99.6% over the wide range of 680-1060 nm. They feature neutral Group Delay Dispersion (GDD) and low third order dispersion. Designed to minimize phase distortion when steering ultrashort pulses at 45° AOI, these mirrors are ideal for use with Spectra-Physics ultrafast lasers including the Mai Tai®, Spitfire® Ace™ and Tsunami®.

Our Ultrafast Broadband Turning Mirrors are designed to steer beams at 45 degrees AOI with over 99.6% reflection across the wide 680nm to 1060nm wavelength range. The back surface of the mirror is polished to enable transmission of visible wavelengths in order to monitor relative power.
Careful thin film design and advanced coating processes result in a mirror with maximum reflectivity, maximum bandwidth and minimum effect on pulse dispersion. Minimizing phase distortion and neutral GDD across the tuning range, these mirrors are ideal for use with ultrafast lasers.
Our ultrafast mirrors may be used as dichroic mirrors in pump probe laser applications. The mirrors have a 30 arc minute wedge angle to suppress interference fringes for the transmitted beam. Note that performance outside of the specified wavelength range cannot be guaranteed.
In two photon microscopy, biological samples are illuminated with focused ultrashort pulsed infrared lasers. At the focal point molecules may absorb two photons then fluoresce in the visible range. These incident pulses often span a very broad wavelength range. Intensity of the fluorescence signal depends strongly on laser pulse width and peak power. Our mirrors allow redirection of Ti Sapphire beams for all possible wavelength ranges with minimal power loss and pulse broadening for optimal system efficiency.
Spectra-Physics Ultrafast Lasers have a polarized exit beam. For optimized performance, it is important to select a mirror with matching polarization. Both the Mai Tai® laser and Spitfire® Pro lasers have a horizontally polarized output beam, so choose the 10Q20UF.35P mirror. The Spectra-Physics Tsunami® has a vertically polarized output beam, so choose the 10Q20UF.35S mirror.
Fused Silica is synthetic amorphous silicon dioxide of extremely high purity. This non-crystalline, colorless silica glass combines a low content of inclusions with high refractive index homogeneity, a very low thermal expansion coefficient, and excellent transmittance in the wavelength regime from UV to NIR. As a result, these mirrors will perform better with temperature fluctuations and is ideal for high-energy laser applications due to its high energy damage threshold.
