VBG FAQs
- Can you also provide near 100% reflectivity?
- Do you offer low power (100 mW) laser diodes in the near infrared (800 – 900 nm) that are frequency stabilized using VBG?
- How big are the wafers you can produce with your technology?
- How should I determine the optimum reflectivity of the VBG when I use it for wavelength stabilization?
- How stable is the grating on the temperature? What is the usable temperature range
- Is there a big price difference for various reflectivities?
- Is there a possibility to tune the reflectivity peak by changing the temperature or other parameters? What is the dLambda/dTemp coefficient?
- Is there any angular dependence of the peak wavelength? If yes, please give details.
- What is the damage threshold and long-time stability for these VGBs (example: laser diode bar with emitter 1 umx10 mm, power 50 W)?
- What is the optimum reflectivity when used for the above purpose (stabilizing the wavelength of laser diodes used in pumping solid-state lasers)?
- What is the typical thickness of the VGB itself in the glass wafer in order to achieve the near 100% reflectivity?
- What is the typical thickness of the wafers?
- What is the useful range of wavelengths?
- What was the thickness of your samples with 99.9% reflectivity?
