I think you can via spectrophotometer to measurement . usally some crystal company not write label for this.
Lasertec designs, grows, manufactures, and supplies the highest quality crystal and precision optics products, lenses, coatings for laser application

Just a guess, but is this it perhaps? http://cgi.cafr.ebay.ca/JDS-Uniphase...QQcmdZViewItem
If that auction is the right thing then it'd probably be for 808nm -> 1064nm at relatively low powers/high efficiencies.

ITU suggests its a ND wedge cut for communications, not freuqency doubling.
FSR is free spectral range, a term used with narrow frequency fiber lasers for communication and for laser spectrum analysers
sorry, but looks like you have a fiber comms crystal, not a doubler.
