Mirrors

Our laser mirrors deliver an unmatched combination of high reflectivity, high damage threshold, excellent mechanical durability and long operational lifetime. The technology employed to fabricate these high performance mirrors has evolved from our extensive experience in producing optics for some of the world’s most demanding laser systems and applications. These include the world’s largest laser system (at the Lawrence Livermore National Laboratory National Ignition Facility) and beam delivery optics for state-of-the-art microlithography tools. From substrate preparation and thin film coating through product packaging, the same expertise and care that goes into the manufacture of these cutting edge products is applied to the stock and custom built optics available to you.

We offer a variety of stock excimer, ultrafast and solid state laser mirrors for use in ArF, KrF, Ti:Sapphire, and Nd:Yag laser systems. Our stock products cover a broad range of the most commonly required specifications, in terms of wavelength, size, reflectivity and angle of incidence.

However, these stock products represent just a small sampling of our production capabilities. The bulk of our business is devoted to the manufacture of optics built to customer supplied specifications. We can readily produce optics customized in virtually every aspect, including size, shape, substrate material, surface specifications and performance characteristics. Please contact our technical sales department to discuss your custom optics requirements.

Ultrafast
Ti:Sapphire Mirrors

ARO ultrafast mirrors are designed to deliver superior performance for demanding beam steering tasks in Ti:Sapphire laser applications. Close cooperation between the ARO design staff and leading ultrafast researchers has enabled us develop to optics that deliver an optimum combination of high reflectivity, broad spectral bandwidth, excellent laser damage resistance and minimal group velocity dispersion. ARO supplies two standard series of ultrafast laser mirrors. Our B-Max coatings are optimized to deliver the Broadest possible bandwidth, while our E-Max high reflectors are specifically optimized to attain the highest pulse Energy damage threshold. In addition to these stock components, ARO can readily produce optics customized in virtually every aspect, including size, shape, substrate material, surface specifications and performance characteristics.

Ultrafast
SPECTRAL SHAPER

Our unique Spectral Shaping Filter provides a simple route to shorter pulses (as short as 10 femtoseconds) from Titanium:sapphire ultrafast amplifiers. This new intra-cavity optic is a dielectric coated filter with a spectral transmission curve designed to precisely compensate for the wavelength dependence of the Titanium:sapphire gain curve. Since the center wavelengths near 800 nm are preferentially amplified, the amplified pulse is effectively narrowed in wavelength. (Spectral narrowing results in pulse lengthening in transform-limited laser pulses). The ARO spectral shaper is an intra-cavity coated optic that has a transmission curve that is the mirror image of the Ti:S gain curve. With this optic inserted in a amplifier, the spectral curve for single pass cavity gain is now a flat line rather than a gaussian. Both the center wavelength and the magnitude of the single-pass gain correction can be easily adjusted with the Spectral Shaping Filter. Specifically, varying the angle of incidence at which the optic is mounted causes a shift in the center wavelength. This enables the filter’s performance to be matched to the skewed spectral gain curve of chirped amplifiers. And, by rotating the filter angle relative to the beam polarization, its transmission maximum can be smoothly increased or decreased. This allows the same filter to be used in both a multi-pass or regenerative type amplifier. The particular performance specifications of the Spectral Shaper can be optimized for OEM’s upon request. For more detailed information on how the spectral shaper works, see the ARO technical white paper entitled “The ARO Gain Flattener for Ultrafast Amplifiers.”
