Specifications

Features

Simultaneous Reflectance for S- and P- Polarized Light

Newport's Low GVD Ultrafast Mirrors have over 99% reflectance from 730-870nm for P-polarization, and 700-930nm for S-polarization. Mirrors are optimized for 45° AOI.

Low Group Velocity Dispersion

These mirrors feature thin film coatings designed to minimize GVD.

GVD and the Cubic Term

Group velocity dispersion (GVD) and the cubic term of the phase expansion are shown for reference. True mirror performance can be affected by manufacturing tolerances and repeatability. Newport minimizes these effects with the use of state-of-the-art thin film production equipment and computer controlled processes. These mirrors have been successfully field tested at several university and industrial laboratories engaged in ultrafast studies and have been found to have high performance very closely matching these calculated curves.

UF.25 Ultrafast Mirror Coating

Our UF.25 ultrafast mirror coating is designed to provide maximum reflectivity and bandwidth with minimum effect on pulse dispersion. This coating is intended for use with ultrashort pulse lasers as a high reflectance beamsteering mirror at 45° angle of incidence. Careful thin film design and an advanced coating process results in a broadband mirror with exceptional performance characteristics. Maximum reflectivity and bandwidth are attained by using these mirrors with s-polarized light.

High Optical Quality Substrate

Our Low GVD Ultrafast Mirrors feature flat BK-7 substrates. The mirrors have surface flatness of λ/10, and surface quality of 10-5 scratch-dig.

High Laser Damage Threshold

Our ultrafast laser mirrors have been laboratory tested for laser damage. They were found to withstand 1 TW/cm2 peak power with 100 fsec pulses at 5 kHz at 800 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 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.

Leaky Mirror

The rear surface of the low GVD ultrafast mirror is uncoated and polished to allow undistorted transmission of leaked ultrafast beams. A tiny component of incident ultrafast beam will transmit through the mirror and may be measured to characterize the ultrafast pulses.
