What is "kl?

KL, often referring to Krypton Laser, is a type of gas laser that utilizes krypton gas as its active lasing medium. It emits light at several discrete wavelengths in the visible spectrum, primarily in the red, yellow, green, and blue regions.

Key characteristics include:

• Wavelengths: Unlike some other lasers that emit at a single wavelength, Krypton lasers produce multiple wavelengths simultaneously, making them useful for applications requiring a range of colors.
• Applications: Common applications include laser light shows, scientific research (spectroscopy), and medical procedures (especially dermatological applications requiring specific wavelengths).
• Power Output: Krypton lasers generally have a moderate power output, typically ranging from milliwatts to several watts.
• Types: There are variations such as the Krypton-Argon Laser, which combines krypton and argon gas to produce an even wider range of wavelengths.
• Safety: Like all lasers, Laser Safety considerations are crucial when operating or working near Krypton lasers, including proper eye protection.
