BFi OPTiLAS est spécialisé dans la fourniture de sources lasers, de diagnostiques et de composants optiques pour les impulsions brèves.

Pour des impulsions <100fs, la réflectivité, la largeur spectrale et le contrôle de la dispersion deviennent des paramètres cruciaux pour le transport du faisceau.

Grâce à nos deux fournisseurs CVI Melles Griot, FEMTOLASERS, nous pouvons répondre à vos demandes pour des impulsions <7fs et pour des hautes tenues au flux.

The TLM2 mirrors are specially designed to achieve high reflectivity and low dispersion for cw oscillators and low-fluence pulses.
These mirrors can be coated for any angle of incidence from 0° to 60° and any center wavelength between 450 nm and 2100 nm.
For 45° tuning mirror applications involving very short pulses or very broad bandwidths, CVI Melles Griot recommends using s polarization if possible. This minimizes pulse distortion and maximizes average reflectivity.
Check that the bandwidth is realistic by using the table on the bottom of the page, then specify the exact center wavelength and all other parameters in the ordering blocks

For application at user-specified wavelengths, these single stack, high-damage-threshold mirrors have become the industry standard. Damage threshold is greater than 20 J/cm 2 depending on such factors as pulse width, repetition rate, and exact beam profile.

Traditional high damage mirrors are limited in bandwidth. Broader reflectivity bands can be achieved by using different coating materials, but that reduces the damage threshold.
Through active research in different coating methods and materials, CVI Melles Griot has designed this mirror which is a high performer in all three areas: high reflectivity, broad bandwidth, and high damage threshold.
It combines the benefits of a broadband low dispersion mirror with those of a high damage threshold high reflector.

BS1 high energy beamsplitters are plate windows coated with an all-dielectric coating to separate laser light into your choice of R/T split ratios.
The BS1 high energy plate beamsplitters exhibit almost no absorption and are designed specifically for 45° at the wavelength and polarization of interest.

Standard substrates have an anti-reflection coating on the second surface and a wedge of less than five arc minutes.

However, the beamsplitter coating can be done on any CVI wedged or plane parallel substrate to meet you application requirements.

• Reflectivity tailored to your exact requirements
• Beamsplitters centered at any wavelength, 193-2940nm

• Broadband Low Dispersion Polarizers TFPK
• Contacted Polarizing Beamsplitter Cubes PBSO
• High-Energy Broadband Polarizing Cube Beamsplitters PBSK

Serie PS & PG: Protected Silver & Gold Mirrors are Less sensitive to variations, in incident angle, polarization and wavelength than dielectric coatings.

• Substrate material:BK7 glass
  
• 60-10µm including Ti:Sa range
  

Accurate dispersion management is an essential prerequisite in any femtosecond laser application. Broadband, low dispersion optical components are needed for manipulating femtosecond pulses.
Accurate compression has to be employed in order to compensate for the dispersion of the optical path between the laser and the experimental target.
These requirements often go beyond the capabilities of standard optical components. FEMTOLASERS, a leader in ultrafast laser equipment, offers the FEMTOOPTICS™ product family, tailored to respond to the optical needs of the femtosecond laser community.

In contrast to products offered by other manufacturers, FEMTOOPTICS™ are optimized for femtosecond pulse manipulation. Transmission optics are as thin as possible, AR-coatings are ultra broadband, metallic mirrors have low dispersion dielectric overcoatings.
Focusing optics and waveplates are optimized both in terms of group delay dispersion and chromatic aberrations. Furthermore a wide variety of dispersive mirror compressors tested in our lab can be supplied.
We also offer custom optics.
