Three years ago, after friends introduced, I played the Rappelz game. At that time, I dazed and confused, I like to go my own way, I have a lot of rappelz rupees, but I became the most evil villains in the game. Until I encountered her, I found the meaning of survival.

The friend took me to the game, but she own was leaving the game. A person to game is boring, every day, I only know to upgrade and earn ro zeny. I can not sad dot this mess of feelings and moving. Once, the two boys for me quarreled utterly, until I leaved and tool sad. Later, I found a boy to married, I think perhaps all this to change, and I pray to become a reality, a few days after he disappeared. A person was playing a marriage number, what would it have taken place.

All of you need to take some Laser Physics lessons. Until you get your Ph.D. in laser physics, stop speculating. Just stop it. Make your point, but don’t speculate. Until you actually are making these products or have been in the laser field for many years, you have no right to guess this or that. Do your homework before you talk. Thank You.

You do realize a Q switched laser has an ultra short pulse duration. Meaning your hypothetical laser wouldn’t even come close to the sustained output of a 500 watt continuous wave laser averaged over a given time period.

this is truly amazing.
it make me feel sooo proud to be part of that twenty first century (
now talk about medical applications

I agree, photons do have mass. They are quite ‘light’, though. (I couldn’t resist)

check out the late paul marmet http://www.newtonphysics.on.ca/info/author.html for the real spin on the photon.
particularly spend some time with the article on the fundamental nature of the electron.

not that the math is wrong it really isn’t; it’s the theory behind it.

100 kw laser is nothing. In the book “Solid State Lasers for the Laser Enthusiast” by Daniel Gregory, he provides information on how to build a laser using an Nd:Yag rod with q-switching. One use a 3mm x 50mm rod and the other uses a 6mm x 76mm rod. I believe the bigger rod produces a 16 Megawatt beam and the smaller is around 2 Megawatts. Either of which far exceeds 100 Kilowatts. Here is the website for his company:

Actually, photons are not “attracted to the sun”.
They appear to bend around the sun and other large objects (as seen with gravitational lensing), however this is not due to mutual gravitational attraction.
The light appears to bend because it is actually travelling a straight path through space-time. Because large masses, such as a star, warp space-time around them, they have the effect of bending the apparent light path.
Hope this helps
