A diode-pumped solid-state laser (DPSSL) has self-maintained multi-dimensional optimization. The output property of the DPSSL, including optical power, noise level, and the operation conditions of its individual components, including the drive current and temperature of the laser diode, the temperature of the laser crystals and laser cavity, the drive current of the thermoelectric coolers, is monitored and systematically optimized in real time through automatic electronic control using a microprocessor. Such monitoring and optimization enable the DPSSL to maintain its optimum performance in output power, beam quality, noise level, and stability, throughout its lifetime regardless of component aging and change of environmental conditions. A highly accurate temperature monitoring and control method is also developed.
