An economical eye-safe laser source at 1500 nm based upon a novel Raman crystal BaTeMo2O9 (BTM) is demonstrated for The 1st time. The laser source was produced with a third purchase Stokes change at…
The concept of emission wavelengths lies for the pretty Main of laser technology, dictating many parameters like penetration depth, ability density, and safety actions. It’s no coincidence that Yb:Er:glass and Tm:YAG, two notable laser crystals, are famous for his or her eye-safe wavelengths.
Equally crystals have their special strengths. The choice in between the two relies on the particular software demands.

Figure four(b) presents the next-Stokes emission spectrum for 27.two W incident pump energy. It could be witnessed that only the 2nd-Stokes emission could be observed, though the fundamental and the primary-Stokes emission may be hardly found. This is principally attributed for the successful Raman conversion as well as the minimal transmission at the fundamental laser and the 1st-Stokes laser from the output coupler M4. Based on the Raman laser theoretical product[39], in order to realize productive 2nd-Stokes lasers, the threshold of the next-Stokes laser is needed being sufficiently better than that of the initial-Stokes laser so that the strong initially-Stokes field could be founded, which efficiently depletes the fundamental laser and enhances the second-Stokes attain. The coating design of output coupler M4 realized efficient cascaded Raman conversion. Furthermore, the Raman conversion efficiency was also proficiently improved by cutting down the place dimension of the elemental laser over the diamond and adjusting the polarization way of the elemental laser to match the way of diamond �?11�? The remarkably fixed spectrum of the 2nd-Stokes emission is demonstrated within the inset of Fig. three(b), which reveals a Centre wavelength Found at 1485.nine nm and also a resolution-restricted linewidth of only 0.
