The original thread I helped the OP to design them from the ground up. I've done the same on other forums (ElectroTech). The OP mentions wanting to power lasers with them (if I read that correctly), so I have a passing interest in this thread.

I think the word, "laser" was just a language problem. I think he means a very intense pulse of light.

No need to re-invent the wheel.

There are a few different types illustrated at https://www.google.com/search?q=%2B%22police+lights%22+%2B%22schematic%22&tbm=isch&tbo=u&source=univ&sa=X&ei=wy8qUuabCsrI2gWnnYFw&ved=0CC4QsAQ&biw=1033&bih=736

10 times faster that what? Define normal with respect to what you want, or define what you want.
