Pyroelectric Energy Conversion is an all solid-state thermal-to-electrical energy conversion technique based on the pyroelectric and thermodielectric effects. While both of these effects are historically considered to be low-power, low-efficiency methods to produce electrical energy, tuned novel materials appropriately operated under the proper conditions, PEC can produce electrical power with grid-level power densities and efficiencies. Such technology is power scalable from milli-Watts to Mega-Watts with all the advantages of solid-state operation including unattended maintenance free operation over periods of decades. Perhaps more important is that PEC is heat source agnostic. As such, PEC can be immediately deployed into the traditional hydrocarbon fueled energy infrastructure as well as make alternative energy technologies more practical including, solar thermal, geothermal, and novel nuclear technologies.
Laser Hosts
Crystal Genesis grows and fabricates novel laser gain elements from the monoclinic double tungstate (MDT) family of crystals. Host crystals include KGd(WO4)2, KY(WO4)2, KLu(WO4)2, [also referred to as KGW, KYW, and KLW respectively]. Rare earth dopants include Yb, Nd, Th, Ho, and Er. Other dopants are available on request. The MDT family of laser gain materials offer high gain bandwidths, large absorption and emission cross sections, good thermal properties, and can accept very high dopant concentrations. These attributes make MDT crystals an excellent choice for very high-power thin disk lasers, ultra-short pulse lasers, and tunable lasers. The MDT family of crystals have also been successfully employed for optical cooling applications.
Nonlinear Optics, Electro-Optics, and Photorefractives
Crystal Genesis suite of nonlinear optical (NLO) and electro-optic (EO) crystals include congruent and stoichiometric lithium niobate (LiNbO3) and lithium tantalate (LiTaO3), potassium niobate (KNbO3) strontium barium niobate (SrxBa(1-x)Nb2O6), and tin hypo-thio phosphate [Sn3(PO4)2]. Crystal Genesis has also produced periodical poled structures for quasi-phase matching (QPM) and electro optic modulators using these and other NLO and EO materials. Doping of these materials increase their photorefractive response in optical storage and limiting applications.
