High volume accurate optical solutions producer, REO has unveiled a new line of mirrors that can endorse the broadband function in Ti:S ultra fast lasers.
The mirrors provide third order dispersion (TOD), least group velocity dispersion (GVD) and high reflectivity of greater than 99.7% between 650 and 1100 nm. These features allow near transform-limited pulse performance across the complete Ti:S tuning series.
An ion beam sputtering (IBS) technology is used for coating the mirrors. This technology provides layer thickness accuracy and refractive index required for TOD/GVD specifications and better performance. The IBS technology fabricates a complete densified film with better environmental durability.
The mirrors can be fabricated for operation with an angle of incidence range between 0° and 45°, and are normally delivered on fused silica substrates with a diameter range between 0.25" and 3". The surface quality range of the reflectors is 10 to 5 and their nominal surface flatness is ë/10 at a wavelength of 632.8 nm. REO can tailor the dispersion, bandwidth and center wavelength properties of these coatings and can produce these mirrors on a wide range of customized substrate sizes and materials.
The mirrors are ideal for next-generation ultra fast laser oscillators used in applications such as CEP-stabilized systems, seeding terawatt amplifiers and multi-photon excitation microscopy. The mirrors are also suitable for one-box laser oscillators where outputs and wavelength tuning are altered in a push-button operation.
