NLO CRYSTAL HYGROSCOPY
This information was largely taken from NLO crystal datasheets at Il Photonics, see [N2,N4]
Non-hygroscopic: KTP,
Med-hygroscopic: BBO, LBO
High-hygroscopic: CLBO, D*CDA, KDP, KD*P
HYGROSCOPY DEFINITONS
Non-hygroscopic - unaffected by moisture
Med-hygroscopic - unprotected polished surfaces are susceptible to fogging over in most lab situations
High-hygroscopic - keep in a dry environment, a sealed housing is recommended
[N4] Inrad BBO_DataSheet.pdf
'BBO is moderately hygroscopic, so unprotected polished surfaces are susceptible to fogging over
in most laboratory situations.'
[N2] Crystech lbo.pdf
'Users are advised to provide dry conditions for both the use and preservation of LBO.'
[N2] Crystech clbo.pdf
'CLBO is very hygroscopic, so water absorption will occur in an uncontrolled environment.
The crystal will react with water to form additional phases, which, in turn, will result
in severe degradation of the crystal's optical properties.'
[N2] Crystech kdp.pdf
'KDP, KD*P&LiIO3 is highly hygroscopic and the coating can not be available.
Please keep it in a dry environment, and sealed housing is recommended.'
[N27] Quantum Technology D*CDA Properties, datasheet 707.pdf
'It is extremely soluble in water, about 3kg/litre at room temperature. thus it is very
hygroscopic and must be stored in a desiccator or operated in hermetically sealed cells
filled with dry nitrogen.'
CRYSTAL WORKING TEMPERATURES (ESKMA)
