Lasers are light beams that are powerful enough to travel miles into the sky and cut through lumps of metal. Although they seem like a recent invention, they have been with us for half a century. The first practical laser was built by Theodore H. Maiman at Hughes Research Laboratories in 1960. At the time, lasers were an example of cutting-edge technology. Today, we have lasers at our homes, offices and shopping centres. Whether or not we realise it, all of us use lasers all day. But how many of us understand what they are and how they work?

A basic laser consists of a chamber known as the cavity which is designed to reflect infrared, visible or ultraviolet waves so that they reinforce each other. The cavity can contain either solids, liquids or gases. The choice of the cavity material determines the wavelength of the output. Mirrors are placed at each end of the cavity. One of the mirrors is totally reflective, not allowing any of the energy to pass through them. The other mirror is partially reflective, allowing 5% percent of the energy to pass through them. Through a process known as pumping, energy is introduced into the cavity through an external source.

Principleof laser

The output of a laser is a coherent electromagnetic field. In a coherent beam of electromagnetic energy, all the waves have the same frequency and phase.

Fokussiert nicht richtig zum Punkt. Ist wohl eher ein kleiner Strich wie schonmal von jemanden erwähnt. Trotzdem sehr stark und man kann so einiges damit an Spaß haben. Vorallem bei Nacht.

Due to pumping activity, an electromagnetic field appears inside the laser cavity at the natural frequency of the atoms of the material that fills the cavity. The waves are reflected back and forth between the mirrors. The length of the cavity is such that the reflected waves reinforce each other. The electromagnetic waves in phase with each other emerge from the end of the cavity having a partially reflective mirror. The output is a continuous beam, or a series of brief, intense pulses.

So, since purchasing the 7watt Zeus x, I have been having a lot of fun. Everywhere in my apartment there are burn marks ! Different objects create dazzling effects. Anything glass is especially fun. Outside, once you attach the expander and get the focus just right, you can ignite stuff over 100feet away. The batteries must be fresh and the laser must be perfectly still at those distances. Also got the rgb laser. One thing I especially like is when in white mode, the star caps separate the three colors to really cool effect! So, I just ordered the new dual diode 15 watt blue laser. I’ll let you know how it goes ! Thanks Zeus, I’m having a lot of fun. Though my wife hates these things !!

My biggest worry here is that the spring connecting the batteries to the laser unit extends outside of the housing. This means that unless you are careful, the spring can catch the foam in the case and bend it... which will eventually break it off. This laser is almost the length of my forearm when assembled. Another 1/4 inch to cover that vital part would be fine. Or if not possible, a smaller connecting spring.

When lasers were first invented, they were called “a solution looking for a problem”. Since then they have become ubiquitous finding utility in various applications of modern society ranging from consumer electronics to the military.

Already own a couple of the 7 watt zeus x lasers , and these are like a lightsabre ! love them. So when I saw that there was a 15 watt on sale , I had to look twice ! ,then look twice again... Tried to convince myself that I did not really need this , failed miserably ,lol. This laser is an absolute beast , burns anything instantly , and great for long distance engraving ! So glad I failed to convince myself. LOVE THIS ! LASER HEAVEN ! Thank you zeus , great to do business with you again , so good I bought 2 ! ... now looking at the green 2 watt...LOL

The case this came with is... fine. It needs to be a bit bigger, and with the expectation that buyers might want to put a little more in it than it came with. The charger is hard to get back in and there is no space for extra batteries if you do. Still, cool to have a case included.

I have had my green zeus laser for a couple years now and it is still amazing. I have it setup with the 5x beam expander and it is so dam good. Wish i wouldve waited and gotten the more powerful 2watt one they have now or whatever but this one is still amazing. i made sure i didnt leave it on for over 30 seconds at a time and it seems to be the same brightness still :) 10/10 Worth it.

A note on shipping - I ordered this on a Friday night... so it didn't really get moving until Monday. It took less than 3 days after that. 5 days total, but once it shipped, it moved at crazy fast speed.

I was hesitant to purchase something less than practical for so much money, but I enjoy it every time I use it! This thing feels exactly what you expect a lightsaber to be! And turn that thing on, and anything within 10 feet away from you is in danger of being charred! (Focused just right, I got it to light a firecracker almost 12 feet away!) I don't use it all the time, so I only need to recharge it every few months. For improvement, I would like to see a better charger. Mine always has th red light on, and never turns green, even after sitting for 16 hours. I have to time my charges so I don't ruin anything. The laser has nothing to be complained about! I can even burn things underwater!!!! Remember that for lasers this powerful to NEVER have it on for more than 30 seconds. You don't want the focusing and emitting crystals to start deteriorating on you! Thanks Zeus Lasers!

Using these characteristics of lasers, they are applied in various fields such as optical communication and defence. In the next section, let us look at the various applications of lasers.

I've collected somewhat of an arsenal of Zeus Lasers& accessories including the pro and the X. But every so often I check the website just to see if anything new has come out, and when I saw this I wrestled with it for a while, thinking 'what can 15 watts do that 7 can't? Then it hit me: a whole bunch of ideas starting off with... Igniting things from 20 feet away. So maybe I talked myself into it, but after it arrived only 4 days later and I was able to fulfill all my curiosity with wonder, I felt lucky that I had found out about these when I did.

I purchased two (2) Zeus X 7 Watts Blue Laser over a year ago from this website (Zeus Lasers) giving them 5 Star Ratings for their products overall excellent performance and durability. Now, I purchased and tested the Zeus XTR 15 Watts Blue Laser and its truly having two (2) times the power in all aspect of the device listed speicifications. Beware some other Laser websites listing the same 15 watts blue laser and showing the same products images with price ranging from $400 to $699, but maybe just an imitation or copied device or unverified.

The power is there. Easily ignites material from 20 feet. The beam/dot was a bit thicker than I was expecting, but impressive to see in the day and just absurd at night. USE THE EYE PROTECTION. Or you'll have blue/purple spots in your vision for a half hour... or worse.
