Nd:YAG Multiple Order Dual Wavelength Wave Plates

  • operate at both first and second Nd:YAG laser harmonics
  • retardation tolerance <λ/300

Dual wavelength multiple order wave plates are made of precisely polished quartz. Thickness of the plate is controlled to provide the specified retardation at two wavelengths. The waveplates are offered for Nd:YAG harmonic wavelengths and can be used to separate the harmonic beams by means of a change in their state of polarization. For example: a half wave plate has a net retardation of one harmonic and rotates the plane of polarization by 90°; a full wave plate has a net retardation of other harmonic and rotates the plane of polarization by 180°. The two harmonics will therefore emerge with crossed linear polarizations.
