  1. Yes! Hey, how many nanoseconds in a femtosecond? "A femtosecond is a millionth of a nanosecond" Oh right, Kerr cells in holography, cool! I've seen them on optical tables.... Flash photolysis, yup, been there, tried that, but no joy.... photochemistry can be tricky.....dye lasers are the classic example. Wow, we're going deep into laser tech, cool! TEM baby! Mode lock it down, dog... let's get it absolutely coherent, circularly polarized to one sense and frequency. Luckily we got easier ways to do femtosecond lasing.... don't they have LEDs that can mode lock now....? No, don't stop, keep going! I'd just read about actual pictures of organic chemical reactions, actually observing the reaction mechanisms is totakllly amazing....

  2. T-rays, yes! Don't forget terahertz wave effect on your skin.... And attosecond pulses, really? What's that, 10-¹⁸? (These units are so unbelievably small that a blink would miss quintillions of them. It's an apt scale for the thermal motion of electrons in a molecular bond.) To "see" that motion must require very short wavelengths as well....x-rays, gamma?? (apparently just euv or "soft" x-rays, wow!!)
