…HyperRapid NX Fiber Bragg Grating Manufacturing A deep-UV excimer or ion laser, in conjunction with an interferometer or a phase mask, can create an intense fringe pattern in an irradiated Germanium-doped fiber, inducing a permanent periodic modulation structure known as a Fiber Bragg Grating (FBG).…

PowerLocker® Wavelength Stabilization Gratings

PowerLocker® Wavelength Stabilization Gratings

…Wavelength Stabilization Gratings Coherent’s PowerLocker wavelength stabilization gratings are volume holographic gratings (VHGs, also known as Volume Bragg Gratings, or VBGs) that lock a laser diode’s emission wavelength into a narrowed optical spectrum. This increases the spectral brightness and…

NoiseBlock 90/10 Beamsplitter Filters

NoiseBlock 90/10 Beamsplitter Filters

…Beamsplitter Filters Coherent’s NoiseBlock™ 90/10 Beamsplitter Filters are designed to diffract 90% of the incoming light that matches the designed Bragg wavelength (λ0) and incident angle. All other wavelengths will be transmitted through the filter, making them excellent for boosting the effective…
