Abstract
- In this letter, we present a high pulse energy Raman laser at 1946 nm wavelength directly pumped with a 1533 nm custom-made fiber laser. The Raman laser is based on the stimulated Raman scattering (SRS) in an 8-meter carbon dioxide (CO2) filled nested anti-resonant hollow-core fiber (ARHCF). The low energy phonon emission combined with the inherent SRS process along the low-loss fiber allows the generation of high pulse energy up to 15.4 {\mu}J at atmospheric CO2 pressure. The Raman laser exhibits good long-term stability and low relative intensity noise (RIN) of less than 4%. We also investigate the pressure-dependent overlap of the Raman laser line with the absorption band of CO2 at 2 {\mu}m spectral range. Our results constitute a novel and promising technology towards high energy 2 {\mu}m lasers.<br />Comment: I would like to withdrawal this paper because a mistake needs to be corrected.
