Lasers for optical grating mastering
Single frequency DPSS lasers find applications in several optical grating mastering processes due to their ultra-stable output, coherence, and precision. These lasers are essential for creating high quality optical gratings using various mastering techniques and applications.
Optical grating mastering is a process used to create diffraction gratings on optical surfaces such as crystals, semiconductor materials, and specialiced optical coatings.
The gratings have closely spaced parallel lines or grooves that diffract light in specific ways, enabling applications such as spectroscopy, wavelength dispersion, and laser tuning.
Optical grating mastering typically involves using laser interference or etching techniques to apply diffraction patterns on a substrate.
Enables shorter exposure times to reduce disruptive external influences like vibrations.
Power stability and low noise help avoid fluctuations in output power during the optical grating production process that could cause inaccuracy.
Excellent beam quality
Laser output with a well-defined beam profile, low divergence, and pointing stability makes it easier to precisely focus the light source onto the grating surface.
