Fig. 1: Summary of the state-of-art HCFGLs in terms of output, lasing wavelengths and the material absorption of bulk silica.

From: 4.8-μm CO-filled hollow-core silica fiber light source

Fig. 1

Continuous wave (CW) and pulsed outputs are both demonstrated28,29,30,31,32,33,34,35,36,37, with each corresponding to the power and energy on the left y axis, respectively. The red star symbols are the results in this work. The absorption loss of the silica material is represented by the yellow curve (right y axis) and originates from the Heraeus F300 fused silica glass43,44. The vertical dashed line indicates the absorption loss of the silica material at 4824 nm
