Part Numbering System for bulk OPO crystals

C - θ - φ - S - D - L - T - P

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

θ – Orientation in Z-X direction [degrees]

φ - 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]
