Our environmental monitoring startup in San Francisco is developing a methane detection system based on tunable diode laser absorption spectroscopy. What is the best laser type for precise wavelength tuning?

Developing precision gas detection sensors in San Francisco requires light sources with an incredibly narrow spectral linewidth. For accurate methane absorption spectroscopy, you need a high-quality distributed feedback laser to target the specific molecular resonances. The integrated grating structure provides the exact wavelength stability required by US environmental standards
