Integrated Wavelength Control for Diode-Pumped Lasers
Wavelength-stabilized pump diodes can enhance solid-state laser performance.
by Dr. Robert S. Williamson III, Alfalight Inc.
Diode-pumped solid-state laser systems are replacing flashlamp-pumped lasers in many applications because diode pumping results in better overall wall-plug efficiency and beam quality than lamp pumping. Furthermore, diode pumping is the only feasible approach to energizing recently commercialized architectures such as thin-disk and fiber lasers.
Driven by ever-increasing commercial demand and by government initiatives such as the DARPA SHEDS program and the Air Force LADERA program, the performance of semiconductor pump lasers has continually improved in terms of energy efficiency, available output power and overall package reliability...
