High Damage Threshold KTP/KTA Single Crystal

Potassium Titanyl Phosphate Single Crytal, known as KTP (KTiOPO4), is the most efficient frequency doubling crystal for Nd:YAG/Nd:YVO4 laser systems. KTP is the best non-linear optical crystal for 1064nm pumped OPOs.

Our KTP Crystal Features:

  • High damage threshold, low absorption
  • Devices as large as 15x15X20mm are available
  • Massive production to support industrial customers
  • AR-Coating, mounting and re-polishing service
  • Competitive Price and Huge OEM Discount
  • Free Technical Support
