Scientific Materials Corporation has four programs to meet your needs for special crystal compositions.

Program 1
This program is the supply of spectroscopic samples from crystals previously grown. Prices range from $100 for a sample approximately 3 mm dia. x 5 mm long, to $500 for a 1 cm3 sample. Fabrication charges are extra. YAG, YAlO3, Y2SiO5, LuAG, CaWO4, and SrWO4 are available with numerous dopant ions at various concentrations. Please contact us for current availability of specific compositions.

Program 2
This program is the supply of custom crystals grown for your specific requirements. The cost of these crystals grown with proven dopant/host compositions is $3,000 to $9,000 per crystal depending on the specific dopant/host combination. Special material requirements add to the cost. Typical prices for the YAG host are listed as follows for a crystal of nominal size 28 mm dia. x 75 mm long.

• Other hosts available under this program are: YAlO₃, Y₂SiO₅, CaWO₄, SrWO₄, SrMoO₄,    LuAG, and YLuAG.

Program 3
This program is a growth feasibility study for new dopants in known hosts or new undoped hosts. The nominal cost of this program is $10,000 for a three growth run study. Special material requirements are an added cost.

Program 4
This program is a dopant/host material development program to provide production quality laser crystals. This work is normally performed under contract. The typical costs range from $50,000 to $250,000 depending on the material, growth method, and size requirements.
