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 670nm to 1340nm wavelength range. The back surface of the mirror is polished to enable transmission of visible wavelengths.
Minimal Effect on Pulse Dispersion
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 GVD across the tuning range, these mirrors are ideal for use with ultrafast lasers such as the Spectra-Physics Insight.
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.
For Use With Spectra-Physics Lasers
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.
