HYLM-E Series Narrow-Linewidth Laser Module
The HYLM-E narrow-linewidth module uses a gain chip and dedicated grating external-cavity frequency selection for stable single-frequency output. Highly stable drive electronics can be fitted to reduce frequency and phase noise. Linewidth options are ≤3kHz, ≤5kHz, ≤10kHz, and ≤20kHz, with side-mode suppression above 60dB. Stable construction, mature processing, and volume manufacturing provide output insensitive to vibration and temperature for demanding environments.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift.
