1053nm/1064nm Laser Polarization Beamsplitter Description
1053nm/1064nm Laser Polarization Beamsplitter supports 1053nm and 1064nm simultaneously, specially designed for Nd:YAG laser systems. We have specially designed the film system to ensure that the performance of the two wavelengths is the same.
- S-polarized light suppression: transmittance Ts< 0.01% (reflectivity > 99.99%), almost complete reflection, avoid stray light interference, and improve signal-to-noise ratio.
- Efficient transmission of p-polarized light: transmittance Tp> 99%, maximize energy utilization, and extremely low energy loss.
- In addition, it has a dual angle range to choose from, 45° ±3° (42°–48°) is suitable for compact optical path design. 56° ±3° (53°–59°) is suitable for telephoto systems or special incidence requirements. We use fused silica substrates to avoid scattering losses.

1053nm/1064nm Laser Polarization Beamsplitter Applications
This polarization beam splitter is designed for 1053nm and 1064nm wavelengths and is widely used in high-power laser systems, precision measurements and optical experiments.
- High-power laser system
In industrial laser cutting/welding/drilling equipment and additive manufacturing (3D printing), the beam splitter is often used to separate or synthesize beams of different polarization states, using the characteristics of high reflection of S-polarized light (<0.01% transmission) and high transmission of P-polarized light (>99%), to increase the total power while reducing space occupancy. - Fiber laser and communication system
In fiber amplifiers, such as 1064nm fiber lasers, it is used as a polarization beam splitter to manage the polarization state in the cavity, suppress mode competition, and improve output stability. - LIDAR (laser radar)
In laser ranging and LiDAR systems, polarization beam splitters are used to separate or synthesize the emitted light and the echo light, and eliminate the interference of ambient light such as sunlight reflection through polarization beam splitting, thereby improving the detection efficiency - Ultrafast laser
In chirped pulse amplification (CPA) systems, it acts as a reflector or beam splitter to manage the polarization state of broadband lasers.
