This document is a user guide for 1064 nm free-space isolator, which introduces the usage methods, warranty terms and other information
This document is the user guide for the Thorlabs IO-5-1064-VHP free-space isolator, a device designed to reduce or eliminate optical feedback in laser systems. The guide covers safety precautions, including warnings about powerful permanent magnets, and provides step-by-step instructions for unpacking and initial alignment of the polarizer cells.
| Wavelength | 1064 nm |
|---|---|
| Operating Range | 1059 - 1069 nm |
| Polarizer Type | VHP |
| Maximum Power Density (CW) | 20 kW/cm2 |
| Maximum Power Density (Pulsed) | 2 GW/cm2 |
| Aperture | 5 mm |
| Weight | 0.82 kg |
| Isolation | 35 - 44 dB |
| Transmission | 91% |
The safe power limit is 20 kW/cm2 for continuous wave (CW) operation and 2 GW/cm2 for pulsed operation at 1064 nm with a 20 ns pulse width and 20 Hz repetition rate.
If the laser deviates from the center wavelength, the rotation is no longer the ideal 45 degrees and isolation decreases sharply if the wavelength changes by more than 1%.
All Thorlabs free space isolators are covered by a six-month warranty against defects in materials and workmanship.
