Physics is a science that has many different aspects and subsections within it. Using advanced solid state lasers and fiber lasers allows specific research to be observed and completed for a wide range of scientific fields within physics. Some of the parameters in lasers that can influence the results of any light experiment include:
1. Output Power
2. Wavelength Frequency
3. Pulse Duration
The most common sort of research is done using one of two (or both) laser varieties: pulsed beam lasers and constant beam lasers. The shorter or longer the laser pulse is, the different the spectrum will actually be. Ranges can be from the invisible ultra-violet of 0-385nm, to visible colors of 405nm – 790nm, and then infrared wavelengths of 800nm – 4000nm.
Crystal v. Fiber
There are certain advantages in using crystal lasers and other when using fiber lasers for research. One advantage of fiber lasers is that they are more sensitive and will produce more refined results because of that difference in comparison with traditional crystal lasers. Fiber lasers can also be more compact and reach more refined areas because of the fiber coupling. This makes fiber lasers also more suitable for more practical research applications. Crystal lasers on the other hand have a wider range of spectrum when in operation and therefore can be more flexible when it comes to output.
Lasers & Quantum Physics
Lasers would never have been able to have even been invented if it wasn’t for the strong understanding of fundamentals of physics principles by the scientific community – including quantum theory. Lasers have now become one of the most important research tools when it comes to quantum mechanics and other pivotal research discoveries. For example the Nobel winning discovery of Bose-Einstein condensates (BEC) would not have been possible without laser technology.
Diode lasers are the most used variety for research today, here is some ways how:
- Scientific Research – just about ever university science department in the country uses lasers for some component of their ongoing research programs, for both undergraduate, graduate, and doctoral programs. Lasers interact with matter in very specific ways at the quantum level, therefore making them indispensable for quantum research. Lasers can also be used to create and observe chemical reactions used in life sciences.
- Measurement and analysis – long used for range-finding (first by the military), but also now used for construction like laser measurement devices. Lasers are highly customizable being able to produce specific color or wavelength frequencies, output powers, and scannability
- Medicine – lasers are now being used for advanced surgery practices, leaving smaller scars, less mess, and a better efficacy rate. Lasers can be used with refined instruments which make them perfect for medical practices, both emergency and preventative.
- Manufacturing – lasers can produce functional beams strong enough to mold and melt different manufacturing materials. They can be used with computer systems to produce complex markings in metal, wood, paper, or plastics. Much of the modern household items we see have been laser cut.
- Information Technology – CD’s and DVD’s have long utilized laser information technology. Information is installed on discs via laser and can be read via laser technology. When we checkout at the grocery store all items are scanned by a laser which reads the bar code as information and transmits that to the computer system. Laser printing is now so effective its done in our households, with all modern day personal printers using lasers to print ink.
We can see that lasers reach nearly every aspect of our technological world. But they are also critical to research in the modern day. Physicists are using lasers for greater and more profound research year after year. We are seemingly only at the beginning of laser technologies possible uses, with greater research and more applications being produced. The laser industry is also growing, now exceeding several hundred billion dollars a year worldwide. There is greater demand and greater usage for lasers and that will see the industry continue to grow.
Finding the right sort of laboratory laser for your ongoing research is important. The greater the quality of the laser the greater the quality of your results. Be sure to have an idea of what sort of laser needs you have before making a purchase for your research. What strength do you need? What wavelength? Adjustable power? Adjustable wavelength? Pulse or constant? Fiber coupled or standard? What RMS/4 hrs. stability will you require? The more you know the better you can make the right laser choice. Ask questions if you have them.
