The Ultrafast Broadband Turning Mirrors reflect over 99.6% reflectance over the wide 680-1060 nm range. The mirrors have very low, slightly negative group velocity dispersion and low third order dipsersion, making them the ideal for use with ultrafast lasers such as the Spectra-Physics Tsunami™, or Mai Tai® lasers.

- Optimized for 45° AIO for beam steering
- Ultralow phase distortion with slightly negative GVD
- Uncoated surface is polished for transmission at other wavelengths
- Surface quality 20-10 scratch-dig
- Optimized for choice of P- or S- polarization
Wide Spectral Bandwidth
Our Ultrafast Broadband Turning Mirrors are designed to steer beams at 45 AOI with over 99.6% reflection across the extremely wide 680 to 1060 nm range. The back surface of the mirror is polished to enable transmission of visible wavelengths.
UF.55P Coating for P Polarization Theoretical GDD for UF.55 Coating Minimal Effect on Pulse Dispersion
Ultrafast broadband turning mirrors have a slightly negative group velocity dispersion from 680 to 1060 nm
Slight Wedge to Suppress Interference Effects
Our ultrafast mirrors may be used as dichroic mirrors in pump probe laser applications. The mirrors have a 10 arc minute wedge angle to suppress interference fringes for the transmitted beam. Note that performance outside of the specified wavelength range cannot be guaranteed.
Two Photon Microscopy Applications
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.
