Manufacturer of optical solutions, REO has launched a new broadband mirror series for Ti:S ultrafast lasers. The broadband optics enable advanced ultrafast laser oscillators for applications including CEP-stabilized systems, seeding terawatt amplifiers, and multi-photon excitation microscopy.
Broadband Mirrors for Ultrafast Lasers
The broadband mirrors provide third order dispersion (TOD), minimal group velocity dispersion (GVD), and high reflectivity of above 99.7% at a wavelength range of 650-1100 nm. Therefore, the mirrors facilitate near transform-limited pulse operation across the Ti:S tuning range. The optics are offered on fused silica substrates in the diameter range of 0.25" to 3", and are suitable for operation over the angle of incidence range of 0°-45°.
The optical coatings for the mirrors are fabricated using ion beam sputtering (IBS), while this technology provides the layer thickness and refractive index accuracy required in meeting the specifications of GVD/TOD and performance. In addition, the technology creates a fully densified film with durable environmental stability.
The nominal surface flatness and the surface quality of the optics are ë/10 at 632.8 nm, and 10-5, respectively. REO can fabricate the optical mirrors on various custom substrate sizes and materials, and custom design the dispersion, bandwidth and center wavelength characteristics of the optical coatings.
