Other materials used for periodic poling are wide band gap inorganic crystals like KTP ( resulting in periodically poled KTP, PPKTP ), lithium tantalate, and some organic materials.

Lutetium tantalate ( LuTaO 4 ) is the densest known stable white material ( density 9.81 g / cm 3 ) and therefore is an ideal host for X-ray phosphors.

In April 2005, a team from UCLA announced it had devised a way of producing fusion using a machine that " fits on a lab bench ", using lithium tantalate to generate enough voltage to smash deuterium atoms together.

These include single crystals of lithium tantalate, lithium niobate, lithium borate, berlinite, gallium arsenide, lithium tetraborate, aluminium phosphate, bismuth germanium oxide, polycrystalline zirconium titanate ceramics, high-alumina ceramics, silicon-zinc oxide composite, or dipotassium tartrate.

Two types of devices are currently common : " frequency doublers, " often based on lithium niobate ( LN ), lithium tantalate ( LT ), potassium titanyl phosphate ( KTP ) or lithium triborate ( LBO ), and " frequency triplers " typically made of potassium dihydrogen phosphate ( KDP ).

For example, lithium tantalate, LiTaO 3, films are desirable for their non-linear optical properties and have been prepared by first reacting tantalum ( V ) ethoxide with lithium dipivaloylmethanate, LiCH ( COC ( CH 3 ) 3 ) 2, to prepare a precursor suitable for metalorganic vapour phase epitaxy ( a form of chemical vapor deposition ).

Lutetium tantalate itself is weakly rare earth dopants during the crystal growth process, for example with europium ( sharp red line at 610 nm ), samarium ( red : 610 nm ), terbium ( green-yellow : 495 and 545 nm lines ), praseodymium ( red : 615 nm ), thulium ( blue : 455 nm ), dysprosium ( orange : 580 nm ) or niobium ( blue : 400 nm, broad peak ).
