Hydrothermal Crystal Growth that Eliminates Spontaneous Emission
This hydrothermal approach to growing single crystal oxide hosts resolves the issues posed by amplified spontaneous emission (ASE). ASE is the result of unwanted internal reflection of photons at the lasing frequency within the laser crystal. The consequences of ASE include induced emission of ions from the excited state and unwanted internal lasing...
