Volume holographic gratings have recently attracted interest as wavelength-selective devices, for applications
such as wavelength stabilizers for laser diode sources. These thick gratings are usually produced using various
photosensitive materials like photo-thermo-refractive glass and specially prepared polymers. These materials
often require two or more process steps for production of volume holographic gratings. In this study several
copolymers with MethylMethAcrylate as base material are compared. Unlike commercially available PMMA,
the polymers have a glass transition temperature up to 155 °C, which enables the use on higher laser powers.
The refractive index of the polymer is modified using 325-nm-radiation. The polymers were not sensitized by
peroxidation prior to irradiation, and after the irradiation process, no development was needed. The gratings
were recorded with both a Lloyd mirror setup and the well-known phase mask method. The gratings produced
have a calculated refractive index variation in the range of 10<sup>-5</sup>. The reflection characteristics were measured
with a modified Michelson interferometer and a tunable laser source. Volume holographic gratings with extremely
narrow bandwidth and angular selectivity can be produced on some of the polymers. The production cost of
the gratings is low and they can be used for multiple applications such as wavelength tuning and wavelength
selection of diode lasers at high power levels.
