    I think it is for 473nm but not sure.

    I think you can via spectrophotometer to measurement . usally some crystal company not write label for this.

    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.
