Features

High Reflectance UF.25 Ultrafast Coating

UF.25 ultrafast mirror coating is designed to provide maximum reflectivity and bandwidth with minimum effect on pulse dispersion. Careful thin film design and an advanced coating process result in a broadband mirror with exceptional performance characteristics. This coating is optimized at 45° AOI for steering ultrafast pulsed lasers and provides simultaneous reflectance for both S- and P-polarized light, over 99% reflectance from 730-870nm for P-polarization and 700-930nm for S-polarization.

Low GDD and the Cubic Term

Group delay dispersion (GDD) and the cubic term of the phase expansion are shown below 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.

Leaky Mirror

The rear surface of the low GDD 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.

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.

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.

High Optical Quality Substrate

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

N-BK7 Substrates

N-BK7 is a relatively hard Borosilicate glass that offers good scratch resistance with a very low level of inclusions.

Fused Silica Substrates

Fused Silica is a high quality mirror substrate offering excellent λ/10 surface flatness and 15-5 scratch-dig surface quality.
