These glasses can operate with intensities up to 20 GW/cm2. 8a), an input light is launched into the polarizer to provide a linear and vertical polarized light beam (s-polarization). 8.In the forward direction operation (Fig.
We can also offer rotators based on super-resistive Ce-doped glasses for high-power applications. An example of a two-stage, polarization-dependent optical isolator is shown in Fig. In addition we can offer relatively inexpensive rotators and isolators operating at any given wavelength within the 213-1400 nm range with clear apertures of up to 100 mm, as pictured to the right. To fill the gap, Passat has developed a unique new family of cooled Faraday rotators specially designed for integration into high-power laser systems (up to 1 kW), see picture at the left. As the applications for more powerful lasers expand, this becomes a serious limitation. The use of low-inductance micro-transformers in the ISOW7841 device necessitates the use of high- frequency switching, resulting in higher radiated emissions. Suite H Garden Grove, CA 92841 United States. Our polarization-maintaining Faraday isolator features low insertion loss, high isolation. The specifications for selected models are listed in the table below.Īt higher powers the extinction drops dramatically due to heating of the rod. Find suppliers for Faraday isolators in the RP Photonics Buyers Guide. These models are suitable for both CW and pulsed applications. In principle, the function of an optical isolator is analogue to that of an electrical diode. For 1 ns pulses, the damage threshold can be as high as 5-7 GW/cm2. of operation is based on the Faraday effect (linear magneto-optical effect). They are able to operate at average power levels of up to 20 W for the Tb-glass models and 50 W for the TGG crystal models. Product Specifications View similar products. Then the reflected light can be cut off by the polarizer at the input end while the. The FR43 from Micro Harmonics is a Waveguide Isolator with Frequency 170 to 260 GHz, Bandwidth 90 GHz, Insertion Loss 1.9 to 3.8 dB, Power 0.6 W, Isolation 18 to 20 dB. Our standard models (pictured above) operate at 1064 nm. The Faraday rotator rotates the polarization of incident light by 45.
