High Efficiency and Beam Quality: Q-Switched Lasers
Q-switched lasers are a type of laser that produces very short, high-energy pulses of light. The term „Q-switched” refers to a technique used to modulate the quality factor (Q) of the laser cavity, effectively trapping and then rapidly releasing energy in the form of a high-intensity pulse. This technique is crucial for applications requiring high peak power and extremely short pulse durations, typically in the nanosecond to picosecond range. Q-switched lasers are widely used in various fields, including industrial processing, medical treatments, scientific research, and telecommunications.
Key Benefits
