The second type, Adjustable Narrowband Isolators, offers the user the ability to adjust the alignment of the input and output polarizers, allowing tuning of the center wavelength within a 45 nm range. Any deviation from this wavelength will cause a dip in isolation and transmission. The first type, Fixed Narrowband Isolators, contains fixed, factory-aligned optics, for which peak isolation and peak transmission occurs at a pre-defined center wavelength. Please see the Isolator Tutorial tab for an explanation of the operating principles of a Faraday isolator.įor applications at Nd:YAG wavelengths, we offer three types of isolators. In addition, intense back-reflected light can permanently damage optics. Back reflections can create a number of instabilities in light sources, including intensity noise, frequency shifts, mode hopping, and loss of mode lock. Optical isolators, also known as Faraday isolators, are magneto-optic devices that preferentially transmit light along a single direction, shielding upstream optics from back reflections. Thorlabs is pleased to stock a variety of free-space optical isolators designed for use with Nd:YAG lasers (i.e., output at the fundamental wavelength of 1064 nm). Max Beam Diameter from Ø1.6 mm to Ø9 mm.Isolation at Center Wavelength from 25 to 55 dB.IO-3-1064-HP Isolator Shown in Included SM1RC Saddle and Mounted to an Optical Table Using a BA1 Base and SD1 1/4"-20 to 8-32 Counterbore Adapter Features
