 ■PPMgSLT (Periodically poled MgSLT)
PP-MgSLN/PP-MgSLT

QPM wavelength conversion devices

-Material:
  MgO 1 mol% doped Stoichiometric LiTaO3 (MgSLT)
-Applications:
  SHG for visible light oscillation
  OPO and OPG for MIR generation and Quantum
  communications

Please visit SWING website for more information.

 ■Main features of PPMgSLT
Our PPMgSLT devices are fabricated from an effective novel material, MgSLT with reduced nonstoichiometric defects:
(1) High power application
  16W generated using green laser without resonator
(2) Wide aperture
  5 x 5 mm device available (OPO/OPG applications)
(3) UV available by QPM
 ■Typical Device Features
Bulk QPM device for 532nm SHG
  Material : MgSLT
  Size: ~2mm W x 10 / 15 / 20 / 30mm L available
  Thickness: 0.5, and now also 1mm
  PM temperature: 30-40 degrees C
    (customized temperature available also)
  AR coating:
    Standard spec: R<0.5% at 1064nm and 532nm


Advantages compared to LBO:
  Can be operated at lower temperatures for 532nm
  FOM over 50 times higher (FOM= deff2 / n1 x n2 x n3)





Bulk QPM device for OPO/OPG
  Material : MgSLT
  Size: ~5mm W x 10 / 15 / 20 / 30mm L available
  Thickness: max. 5mm
