Part Numbering System for bulk OPO crystals

C - �� - �� - S - D - L - T - P

C - Crystal Type: K (KTP)，HGTR KTP (H)� R(RTP)� L(LBO)� B (BBO)

�� � Orientation in Z-X direction [degrees]

�� - Orientation in X-Y direction [degrees]

S - OPO type: R (regular)� M (monolithic)� D-(double pass)� N (uncoated)

D - Cross Section [mm]

L - Crystal Length [mm]

T � Transmission of signal wavelength on output face [%]

P � Pump Wavelength [nm]

Examples:

KTP OPO� Cross-section 5x5mm� Length 30mm� Regular� ��=90^O�?#966; = 0^O� Transmission of signal wavelength on output T>99.5%� Pump 1064 nm.
