But the DTD does have an impressive mastering facility, where it has now produced 170 different holograms since 1991, with three tables and an argon and a krypton laser
(each at 1W output) and a NdYag frequency-doubled 300mW laser.
It has also installed design, mastering and embossing facilities in-house, with one mastering table using a 4W argon laser to master viewable holograms, and another using a 4W krypton laser
to master diffraction gratings and holographic optical elements, primarily for research projects.
The global medical laser systems market segmentation is based on product types (diode lasers, solid state lasers, holmium yttrium aluminum garnet lasers, erbium yttrium aluminum garnet lasers, neodymium yttrium aluminum garnet lasers, potassium titanyl phosphate lasers, alexandrite lasers, ruby lasers, gas lasers, CO2 lasers, argon lasers, krypton lasers
, metal vapor lasers, helium-neon lasers, excimer lasers , dye lasers) and its applications (cardiovascular, dentistry, dermatology, gynecology, ophthalmology, urology).
