Page 3: Chapter 1 Description
Chapter 1: Description Chapter 1 Description 1.1. Overview The electro-optic amplitude modulator (EO-AM) is a Pockels cell type modulator consisting of two lithium niobate crystals packaged in a compact housing with an RF input connector. Voltage applied across the crystal structure induces change indices... -

λ is the optical wavelength in nm. 1.2. EO Amplitude Modulator Versions Thorlabs offers the EO amplitude modulators in two basic versions: 1. DC-coupled Broadband Version: The electro-optic crystal is directly coupled to the RF modulation input connector allowing the full bandwidth of the crystal to be utilized. The broadband version can be driven from DC up to the frequency limit of the RF driver. -

Page 6: Chapter 2 Setup
WARNING Do not drop or bang modulator. While Thorlabs supplies a rugged enclosure, excessive mechanical shock will damage the LiNbO3 crystal. 2.2. Alignment The EO-AM can be used as a variable waveplate without additional optics. Maximum amplitude modulation requires both polarized input and a polarizer/analyzer at the output. -
Page 7: Chapter 3 Photorefractive Limits
(gray tracking). Photorefractive limits are a concern in the visible region (400 – 700 nm) particularly with frequency- doubled lasers. The lithium niobate crystals in Thorlabs’ EO modulators are MgO-doped for increased resistance to photorefractive damage. Chapter 4 Cleaning and Maintenance Under normal operating conditions, the modulator needs very little, if any maintenance. -
