Laser polarizers are used despite lasers emitting polarized light to further refine the polarization quality and eliminate any residual unwanted polarization states. Specific applications include enhancing the performance of optical systems, improving image quality in microscopy, and ensuring consistent light properties in laser cutting and engraving. While it is true that adding a polarizer can reduce intensity due to absorption and reflection, it can also improve the coherence and uniformity of the beam. In high-precision applications, the benefits of using a polarizer often outweigh the drawbacks. Understanding the role of polarizers is essential for optimizing laser performance in various fields.
