ARTICLE OF THE HOUR Solid-State Lasers
Lower Noise Means Higher Performance
Optimizing the power and repetition rate of pulsed solid-state lasers allows materials processing at high resolution and high speed, a condition made possible by advances in intracavity harmonic generation. Many linear materials proceseqsing applications call for lasers with continuous-wave (CW) output. For example, early stereolithography systems were based on CW lasers such as argon-ion or HeCd. To use a pulsed, Q-switched diode-pumped solid-state laser in this type of application, the...
