Product Description

Product Description
Brewster windows are uncoated optical components that are specifically designed to minimize reflection losses for light with a particular polarization. They are typically made of materials like fused silica or sapphire, and their surfaces are precisely angled to achieve a specific angle of incidence, known as Brewster's angle.   

At Brewster's angle, the reflection coefficient for light with a particular polarization (usually p-polarized light) becomes zero. This means that almost all of the light of that polarization can pass through the window without being reflected. The other polarization (s-polarized light) is partially reflected.   

Applications:
- Laser cavities: They can be used to ensure that the laser beam remains linearly polarized, which is often essential for optimal performance.   
- Polarizers: They can be used in combination with other optical elements to create polarizers, which selectively transmit or block light of a particular polarization.   
- Optical isolators: They can be used in conjunction with Faraday rotators to create optical isolators, which prevent reflected light from interfering with the operation of a laser or other optical system.
- Optical amplifiers: They can be used to reduce reflection losses in optical amplifiers, which can improve their efficiency and output power.
