Abstract
The short-wave infrared band correlated light source, especially near the 2.3 μm band, has a wide application prospect in the fields of optical metrology of combustion process and non-invasive blood glucose measurement. Especially, the 2.3 μm narrow linewidth source has unique advantages in the monitoring of polluted gas and as the pumping source of gas laser. Tm doped fiber laser is an effective method to realize narrow linewidth output in 2.3 μm band. At present, however, the output power of the 2.3 μm band narrow linewidth Tm fiber laser is only in the order of one hundred milliwatts. Here, we demonstrated the first watts-level single-frequency Tm3+-doped fiber laser operating at 2.3 μm.
