8.5W Linear and 3.6W Ring TEM00 Diode-Pumped Alexandrite Lasers

Wavelength tunable and single frequency laser sources in the near-infrared are essential in addressing high resolution applications including Quantum Technologies and remote sensing. Alexandrite lasers are an attractive prospect for these applications owing to its broad emission in the near infrared (700-850 nm) and the commercial availability of high power and low-cost red-diode pumping for high efficiency laser operation in a compact system. Here, we present record-levels of TEM 00 power from diode-pumped Alexandrite linear and ring lasers.
