The spectroscopic characteristics and laser properties of emerald were investigated. The laser measurements showed that the emerald laser tuning range was 720-842 nm and exhibited a high gain and high efficiency in the 760-790 nm range. Under a crystal growth development program, the laser loss has been reduced from 11%/cm to 0.4%/cm. The limiting factor in the laser efficiency is the excited state absorption (ESA). The ESA was measured by two methods: A laser-pumped single-pass gain method, which is generally applicable to all tunable laser materials, and a laser-pumped laser method. A 76% laser quantum yield was obtained in high optical quality emerald. The maximum yield is estimated to be 83%, based on the ESA measurements.
