Product Description
KDP & DKDP Nonlinear Crystals for High-Power Laser Applications
KDP (Potassium Dihydrogen Phosphate) and DKDP (Potassium Dideuterium Phosphate) crystals are manufactured using advanced water-solution growth methods, enabling production of exceptionally large components at competitive costs. These crystals are specifically engineered for frequency conversion applications including second-harmonic generation (SHG), third-harmonic generation (THG), and fourth-harmonic generation (FHG) of Nd:YAG lasers operating at 1064nm.
Key Performance Characteristics
- Excellent UV transmission capabilities
- High damage threshold: 1GW/cm² @1064nm, 10ns, 10Hz (uncoated)
- Superior birefringence properties
- High electro-optical coefficients for modulator applications
- Wide commercial availability and proven reliability
