Laser Focusing Is it possible to create a true laser that uses rf or microwaves?
Since both radio, microwaves, and even x-rays, are on the same frequency spectrum, would it be possible to create a focused laser beam of these waves. Why specifically would it work/not work.
Not only is it possible but it has already been done. Masers produce microwave energy that is coherent. Although I don't recomend using Wikipedia for formal study I think this guy did a good job on the article about Mazers. Please check out:
Why does therapy succeed for some patients and not for others? Eugene T. Gendlin addresses that question, and raises many others, in his classic book FOCUSING. Released in 1980, FOCUSING continues to have far-reaching impact on psychoanalysis and other therapeutic methods, searching out the sub-conscious response to contemporary psychotherapy. According to Gendlin, certain people have intuitive abilities that make applying the principles of psychotherapy easy. Others simply have a harder time acclimating themselves to their new thoughts. Using a subtle version of kinesiology, Gendlin has developed a series of Focusing Steps which contain a built-in test: when performed correctly, each step will build towards a growing physical release. This is the body actually letting go of the offending behavior or mindset. The readers learn how to recognize this feeling and become sensitive to their own unconscious desires and fears. FOCUSING seeks to define and teach positive habits to readers seeking physical and emotional healing, either through traditional psychotherapy or through their own study. Dozens of anecdotes and real-life situations are used to illuminate Gendlin's theories and help the reader begin applying his technique immediately.
Focusing--defined as a body-oriented process of self-awareness and emotional healing--is employed today by thousands of psychotherapists with their patients. This book, the first to make the methods of this treatment accessible to laypersons, outlines in friendly, nontechnical language how to effectively use focusing to address a variety of issues.
In accelerator physics strong focusing or alternatinggradient focusing is the principle that the net effect on a particle beam of charged particles passing through alternating field gradients is to make the beam converge. By contrast Weak focusing is the principle that nearby circles, described by charged particles moving in a uniform magnetic field, only intersect once per revolution.Earnshaws theorem shows that simultaneous focussing in two directions at once is impossible. However, ridged poles of a cyclotron or two or more spaced quadrupole magnets (arranged in quadrature) alternately focus horizontally and vertically.

High Quality Content by WIKIPEDIA articles Isoelectric focusing (IEF), also known as electrofocusing, is a technique for separating different molecules by their electric charge differences. It is a type of zone electrophoresis, usually performed in a gel, that takes advantage of the fact that a molecules charge changes with the pH of its surroundings.

"Why can't my laser burn?" - Some Tips on Laser Focusing and Burning
How can i magnify or focus a laser?
I pulled a laser out of a toy gun so it is just the bulb and battery fixtures. what can i do to it or put on it to focus it into a beam or amplify it?
You cannot amplify a laser just like that; you need an optically active medium to amplify light (that's a laser cavity itself). You probably mean "magnify" the light into a beam with a larger waist so that it looks like a nice wide and collimated beam (like a starwars blaster).
That's not an easy thing to do: you need a positive lens with a very short focal distance (your granpa's magnifying glass won't do, I'm afraid) and focus it down onto a small circular aperture (diameter of about 0.5mm, a pinhole poked on aluminum foil might work, but that's hard to get right) and then to pass it though another lens at the focal length of it. We call that "spatial filtering" in optics and requires several optomechanical components. None of these things are available in an average household.
I'm afraid that's rather difficult for the amateur scientist to do properly. Keep that laser beam off your eyes, by the way.
