The SAES Getters Group Announces New Optical-Grade Congruent Lithium Tantalate
Worldwide market leader in getter components for high vacuum applications, by leveraging its expertise in material science and thermal processes SAES Getters has recently entered the advanced material niche markets, starting up also development and manufacturing of crystal substrates used in optoelectronic devices and solid-state lasers.
The new crystal has been developed in response to the increasing interest that optical tantalate is generating in the optoelectronic, laser and display application fields specifically, which particularly exploit its wavelength conversion capability.
SAES Getters' optical-grade congruent lithium tantalate is a high quality, stable and reliable substrate for advanced waveguide-based devices too, such as sensors and frequency converters. Adoption of the Proton Exchange technology, as well as periodic poling, allows highly performant complex optical structures on SAES congruent lithium tantalate substrates, which can be provided in boule and in 2" and 3" wafer configurations.
SAES' advanced optical crystal product line also includes lithium niobate, both in the stoichiometric and optical-grade congruent compositions, high-grade Nd:YAG and LiNbO3 crystals for Q-switching.
About the SAES Getters Group
Pioneering the development of the getter technology, the SAES Getters Group is the world leader in a variety
of scientific and industrial applications where stringent vacuum conditions or ultra high pure gases are
required. For the last 60 years, its getter solutions have been supporting technological innovation in the
information display and lamp industries, in ultra high vacuum systems, in a wide range of electron device-based
applications, and in the vacuum thermal insulation.
The Group also holds a leading position in ultra pure gas handling for the semiconductor and other hi-tech markets.
Starting year 2004, by leveraging the core competencies in special metallurgy and material science, the SAES Getters Group has expanded its business in the advanced material niche markets, with the introduction of: the optical crystal product line, for optoelectronic and solid-state laser applications; the shape memory alloys, for components primarily used in the automotive, transportation and electronic appliance industries; and the metalorganic material product line for chemical vapor deposition.
A total production capacity distributed at 8 manufacturing plants spanning across 3 continents, a worldwide-based sales & service network, nearly 1,000 employees allow the Group to combine multicultural skills and expertise to form a truly global enterprise.
SAES Getters is headquartered near Milan (Italy) and has been listed on the Italian Stock Exchange Market, STAR segment, since 1986. More information at www.saesgetters.com
