Dye Laser and Wavelegnth Selection Gratings

View Grating List

HORIBA Jobin Yvon has developed two types of gratings for dye lasers and wavelength selection: L series (Littrow configuration) and G series (grazing incidence configuration). These holographic gratings are optimized for efficiency when used with TM radiation.

Standard gratings are aluminum coated. Gold coating is offered upon request, to improve efficiency above 600 nm.

Efficiency curves are very flat, and specific blaze wavelengths are not specified. Efficiency vs incidence angle is available upon request.

Ruled area: extends to within a 2-4 mm border around the grating edge.

Standard substrate material is Pyrex; on request, substrates including fused silica, Zerodur, ULE, metals, or other materials can be considered.

Standard coating is aluminum. On request, AlMgF2 , platinum are also available for an additional cost.

NOTE:
These efficiency curves are absolute theoretical efficiencies, calculated using rigorous electromagnetic theory, taking into account the true groove profiles of manufactured gratings measured with an atomic force microscope (AFM). These curves are for reference only and do not indicate grating specifications.
