The Spectra-Physics SP117A Helium-Neon Laser Faraday Isolator is a remarkable piece of optical technology, meticulously designed and engineered for high-performance applications. This isolator is an integral component of laser systems, providing superior stability and beam quality.
The SP117A is a helium-neon laser isolator, harnessing the power of two essential gases, helium, and neon, to generate a coherent, monochromatic, and highly directional light beam. The laser itself emits light at two distinct wavelengths, 632.8 nanometers (red) and 543.3 nanometers (green), making it versatile for a wide range of applications, from spectroscopy and holography to alignment and absolute distance measurement.
The Faraday Isolator in this system is a crucial element that ensures the laser beam maintains its polarization state and eliminates any unwanted optical feedback. The Faraday Rotator, a key component, rotates the polarization of the light as it passes through, while the Polarizing Waveplate and Polarizing Prism ensure the beam maintains a single polarization state while exiting the isolator.
The Spectra-Physics SP117A Helium-Neon Laser Faraday Isolator is renowned for its exceptional stability, with a typical output power of 10 mW at 632.8 nm and 5 mW at 543.3 nm. Its compact, rugged design makes it suitable for various environments, from laboratory benchtops to industrial settings.
In summary, the Spectra-Physics SP117A Helium-Neon Laser Faraday Isolator is a high-performance, versatile, and reliable optical component that delivers consistent, high-quality light beams, ensuring optimal results in a variety of applications.

If necessary. I purchased it from SAM Goldwater but just won't work for my application. Sam is a great resource and offered to answer any questions buyer may have regarding this specific laser. The laser comes with thermal and integrated optical isolation for enhanced stability.
According to laser expert SAM Goldwater, this is one of the highest power tubes he has seen, and isolator built in. E-mail him at SAM sedatives.
