KTP – Potassium titanyl phosphate

350 nm - 4400 nm | >55 J/cm² @ 1064 nm, 10 ns, 10 Hz

KTP (KTiOPO4) is very popular biaxial crystal. It is often grown using either flux or hydrothermal method, however flux growing is approximately 4 times cheaper. This crystal is one of the least expensive options for second harmonic generation (SHG).

• Flux grown – low cost compared to KTA, BBO and LBO;
• Wide transparency range (350 nm to 4.4 µm);
• Broad type II non-critical phase-matching range;
• Hydrothermally grown gray tracking resistant KTP crystals are available upon request;
• Large non-linear optical (NLO) and high electro-optical (E-O) coefficients;
• Efficient frequency conversion (1064nm SHG conversion efficiency of about 80% can be achieved);
• Non-hygroscopic, good chemical and mechanical properties (stability).

Second-Harmonic-Generation (SHG) and Sum-Frequency Mixing (SFM)

• Nd-doped lasers. KTP is most common crystal used for frequency doubling in Nd-doped low and medium power density laser systems.
