In the world of laser, Q-switched lasers have their own identity. They are classified as high-powered lasers which emit extremely short, high-energy pulses of light. Q-switched lasers release energy in intense bursts lasting only a few nanoseconds. This unique capability makes them highly effective for applications that require precision, minimal heat damage, and high peak power. Let’s talk more about these lasers.
Do you know what Q-switch lasers are?
The term Q-switching refers to a technique used to control the quality factor (Q) of a laser cavity. By temporarily storing energy within the laser medium and then releasing it suddenly, Q-switched lasers generate pulses with very high peak power. Common Q-switched laser types include Nd:YAG, Nd:YVO₄, and fiber-based systems. Operating wavelengths are 1064 nm, 532 nm, and 355 nm.
Key features:
- Ultra-short pulse durations
- High peak energy
- Precise material interaction
- Minimal thermal impact on surrounding areas
What makes Q-switched lasers ideal for industrial uses?
Offering accuracy, speed and consistency, Q-switch lasers find application across a wide range of industries. These lasers delivercontrolled energy that can modify material surfaces without excessive heat buildup. This makes them suitable for delicate components, high-value materials, and automated production environments.
Key industrial applications of Q-switched lasers:
One of the most widespread uses of Q-switched lasers is permanent marking and engraving. They are used to mark metal parts (steel, aluminum, titanium), plastics and polymers, as well as ceramics and coated materials.
Q-switched lasers are widely used in laser cleaning applications. The short, powerful pulses remove contaminants like rust and oxidation, paint, coatings, oil, grease, and residues. What makes is even more demandable is non-contact, chemical-free cleaning.
Other uses include micro-machining, precision processing, fine cutting, mold and tool maintenance, and so on.
Their industrial demand depends largely on their ability to deliver high-energy pulses with minimal thermal impact. At ERDI Tech Ltd, we provide custom laser products for any industrial requirement.
