An effective eye-safe laser source at 1500 nm based upon a novel Raman crystal BaTeMo2O9 (BTM) is shown for the first time. The laser source was created with a 3rd order Stokes shift at…The fight of eye-safe laser crystals, Yb:Er:glass and Tm:YAG, isn't a lot of a fight as It's really a complementary partnership. Both equally crystals provide exc
