KTP 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

Application:

  • Frequency Doubling (SHG) of Nd-doped Lasers for Green/Red Output (1064~532nm)
  • 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
