Monolithic Second Harmonic Modulators
Monolithic Second Harmonic Modulator

The Modulated Second Harmonic Modulator (MSM) is a device that combines quasi-phase matched second harmonic generation and phase modulation into a single fiber coupled waveguide.

AdvR has a strong history in making fiber coupled frequency conversion devices and high power fiber coupled phase modulators in KTP waveguides. With the MSM, AdvR now offers both capabilities in a single waveguide, allowing for a modulated 532nm output from a 1064nm source, or a modulated 780nm output from a 1560nm source.

These products have seen interest from applications, including frequency locking a 1064nm laser to an iodine reference cell as well as interrogating a rubidium reference cell for use in optical atomic clocks.
