Fiber laser (FLs) not only dissipate thermal energy easily, but they won’t ever go out of alignment and are very tough and compact as well. They share technology with a wide range of other laser types, come in a variety of forms and have their own pros as well. In the case of needed custom work, Midwest Metalcraft includes a Custom Metal Fabrication Division.
What is a fiber laser?
Well, the fiber laser is simply a variation of the solid state laser. In order to emit laser light, the laser uses a dopant that’s mounted in the fiber’s central core, while the core structure can either be very complex or simple. When it comes to fiber lasers, it’s important to mention that surface to volume ratio is quite large, meaning that heat can be dissipated a lot easier.
Features of a fiber laser:
- High power
- Dual core structure
- High efficiency
- Ability to drill concrete
- Can be used in various scientific applications
High-power fiber laser
Fiber lasers are generally useful in the industrial market for a wide range of applications. In addition, it seems that they are generally useful in the automotive industry. In order to manufacture cars, the car industry began to use high strength steel. That’s because it helps them produce lighter, but also more durable vehicles. The only problem they have though is steel cutting high strength steel. Luckily, the use of high power fiber lasers seems to help get the job done. Using regular machines for punching holes in this type of steel is difficult, but not for fiber lasers. Midwest Metalcraft can cut Mild Steel 1″ Plate to 26 GA, Stainless 1” Plate to 26 GA, and Aluminum .190 Plate to .030. Other material are to be reviewed on a job-to-job basis. Our lasers can also do etching if you would like to place part numbers, serial numbers, names, logos, the list goes on and on. Along with cutting we also have a high speed punch press for all kinds of metal materials.
FLs are very efficient
One thing you need to know about FLs is that they’re quasi 3-level systems. This is a very efficient system that can exemplify this very simple example: Using ytterbium with a pump photon of nine hundred and forty nanometers creates a photon at one thousand nm-a (lost energy) of just nine percent.
A four kilowatt multimode fiber laser shows successfully for drilling and also cutting concrete. Why would a fiber laser be useful for such applications in the first place? Well, it’s because it can be effectively useful for developing buildings that boast higher earthquake resistances. In order for the building to resist strong earthquakes, rebar needs put in. Percussion drilling though will only weaken and eventually crack the concrete, but fiber lasers can easily cut it with causing any fractures.
Surface machining is available on transparent materials. One example in this regard is the popular LASIK surgery where surgeons use a femtosecond pulse in order to breakdown the eye material at a specific depth, without damaging the surface. As a result, the cornea exhibits no damage by the process. There are many other medical applications where femtosecond and picosecond fiber lasers are greatly useful, including shallow penetration and OCT.
Easily generated frequency combs seem to have a very realistic near term application for atomic clocks. These are useful for Global Position System satellites and help in getting a much more accurate position resolution. This will be useful for knowing your exact position on the ground, but also for automated equipment, including tractors, cars, robots, etc.
Fiber lasers have a wide range of applications that just keeps on increasing every year. In the future, they’ll be successfully used not only for military applications, but also for next generation industrial application as well.
