There is no single "best" laser in the world, as the ideal laser depends entirely on its intended application. The term "best" requires context – highest power, smallest size, most efficient, etc. However, we can examine some of the world's most powerful and notable lasers:
High-Power Lasers
-
Vulcan 20-20 (UK): This laser, set to be completed in 2029, is projected to become the world's most powerful laser. Its beam will be an astounding one million, billion, billion times brighter than the most intense sunlight. [Source: BBC News, UKRI]
-
ELI NP (Czech Republic): Currently holds the title of the world's most powerful laser, boasting a power of 10 PW (petawatts). [Source: Laser Focus World]
-
Other contenders: Several other facilities around the world are developing exceptionally powerful lasers, constantly pushing the boundaries of what's possible. The "most powerful" title is often a shifting target.
Handheld Lasers
Determining the "best" handheld laser is equally subjective. The Spyder 3 ArcticBlue is marketed as the world's most powerful legally ownable handheld laser, boasting over 3500mW.

Considerations for Choosing a Laser
When determining the "best" laser for a specific purpose, several factors need consideration:
- Power Output: Measured in watts (W) or other units, this is crucial for applications like cutting or material processing.
- Wavelength: Different wavelengths interact differently with materials. The appropriate wavelength is critical for various applications.
- Pulse Duration: For pulsed lasers, the duration of each pulse significantly impacts applications.
- Beam Quality: A high-quality beam is necessary for precise applications.
- Safety: Laser safety is paramount. Appropriate safety measures must be in place depending on the laser's power and wavelength.
While specific examples like the Vulcan 20-20 represent cutting-edge technology in high-power lasers, the "best" laser is always relative to the application. The YouTube videos referenced showcase both high-powered and handheld lasers, but these examples do not represent definitive claims of global superiority.
