Figure_3(a) … feedback_fiber.csv
text/plain (16kB)
The fiber attenuation was measured by using the cut-back method. The Tungsten lamp was used as the whitelight source. A 300 mm focal length scanning spectrometer (Bentham Instruments TMc300) was used for all spectral measurements at mid-infrared wavelengths, which has a 300 lines/mm grating and a liquid-nitrogen-cooled InAs detector (Electro-Optical Systems S-010-LN4).
Figure_3(b)-P(9)_absorption_line.csv
text/plain (496B)
The acetylene (12C2H2) P(9) absorption near 1530 nm was measured by recording the transmission of CW laser after 10 m gain fiber filled with 0.3 mbar acetylene gas. A thermal power meter (Ophir 3A-SH) was used to measure the laser power. The tunable laser diode (ID Photonics GMBH, CoBrite DX1, linewidth <100 kHz, maximum output power ~40 mW) was used as a source after amplification.

The spectral measurements were performed using a 300 mm focal length scanning spectrometer (Bentham Instruments TMc300) fitted with a 300 lines/mm grating and a liquid-nitrogen-cooled InAs detector (Electro-Optical Systems S-010-LN4).
Figure_5(a) … CW_pumping.csv
text/plain (174B)
The pump powers referred to in Figs 5 (a) were measured after the dichroic mirror and before the input lens and window.Measurements of optical powers were performed using a thermal power meter (Ophir 3A-SH).
Figure_5(b) … laser_output.csv
text/plain (1MB)
Stability of laser output as a function of time in the fig 5 (b), was measured at 10 Hz sampling rate over more than one hour. A high gain detector (Thorlab PDA20H-EC) was used to directly measure the lasing power.
Figure_5_(b)_-_Inset.csv
text/plain (17kB)
The mode profile (inset Fig 5 (b)), was measured by using a two-dimensional scan with a short piece of feedback fiber (less than 3 m) across the output beam. The fiber was mounted on a 2D scanning translation device and connected with a high gain detector (Thorlab PDA20H-EC). The whole scan was controlled by LABView software.
