Nonlinear Optical Crystals: KTP
KTP (Potassium Titanyl Phosphate) crystals is the most commonly used material for frequency doubling of Nd-doped lasers, particularly at the low or medium power density.It is widely used for frequency mixing to generate Red/Green/Blue output, and for OPO and OPA to generate visible to mid-infrared tunable output. It is also used for many E-O devices such as Q-switches and E-O modulators.
Advantages:
- Large nonlinear optical coefficient
- Wide angular bandwidth and small walk-off angle
- Broad temperature and spectral bandwidth
- High Electro-Optics(E-O) coefficient and low dielectric constant
- Non-hygroscopic, chemically and mechanically stable
KTP’s Applications
- Frequency Doubling (SHG) of Nd-doped Lasers for Green/Red Output
• Frequency Mixing (SFM) of Nd Laser and Diode Laser for Blue Output
• Parametric Sources (OPG, OPA and OPO) for 600nm – 4500nm Tunable Ouptut
• E-O Modulators, Optical Switches, Directional Couplers
• Optical Waveguides for Integrated NLO and E-O Devices
