Notes:
1. To inquire or order a finished crystal, please provide specifications as listed above. For most applications, we only need to know the following:
1)Nd-dopant concentration; 2)sizes; 3)surface quality; 4) coating.
2. For special request, please provide detailed specification for evaluation and fabrication.
