Question

Quizplus · Accepted Answer

Thulium-doped fiber lasers, when pumped at around 0.786 µm (which is in the near-infrared region), typically emit light in the 2 µm wavelength range. The correct emission wavelength for this setup is approximately 2.3 µm, which falls within the infrared spectrum and is a common output for thulium-doped fiber lasers under such pumping conditions.
