A femtosecond laser is a special type of laser that emits extremely short pulses of light. These pulses are incredibly brief, lasting only a few femtoseconds (fs). To give you an idea of how short that is, one femtosecond is one quadrillionth of a second (10⁻¹⁵ seconds)! Because of these...
What is an Ultraviolet Laser
An ultraviolet laser is a type of laser device that emits ultraviolet light with a wavelength of 355nm. Ultraviolet lasers are characterized by their small spot size, narrow pulse width, multiple wavelengths, high speed, good penetration, low heat generation, high output energy, high peak power, and excellent material absorption. Due...
Laser welding of highly active materials aluminum and copper precautions
High-reflectivity materials reflect a significant portion of the incident light, absorbing relatively little energy. Common high-reflectivity metallic materials include aluminum, copper, gold, and silver. Because of these reflective properties, laser welding of highly active materials like aluminum and copper presents unique challenges. Some high-reflectivity materials can reflect as much as...
