    Basically the water acts like a fiber optics delivering the light to the bottom of the cut. Its very similar to what happens when you cut acrylic with a co2 lasers, the walls of the freshly cut acrylic have the same effect acting as a waveguide which allows you to cut way thicker than the depth of focus of the lens.

    Thats what my calculator says. That said, i need to apologize, i fat-fingered a digit; its not a minimum of .02mm, its .03mm, they advertise a tool diameter of .03mm to .08mm, so 1 to 3 thou

    .02 millimeters, according to the manufacturers website

    If you were to put that laser in a hand held gun would you be able to poke a hole through something across the room??

    Have to ask.......... is this a water jet with a laser on it's head or vise versa??

    The Laser MicroJet (LMJ) is a hybrid method of machining, which combines a laser with a "hair-thin" water jet that precisely guides the laser beam by means of total internal reflection in a manner similar to conventional optical fibers. The water jet continually cools the cutting zone and efficiently removes debris.

    Interesting, total internal reflection is a neat effect to study. 20 years ago or better I used to machine nozzle bodies for a fountain company that used a laminar flow nozzle combined with an LED light source fed to the stream through a fiber optic poly rope. Similar to what's in this video, but much larger.

    Lol. If I only had a NIR Q-switched laser.

    I'd be much more impressed if you mounted it on a shark

    I too have an extensive shopping list, now if I could just guess the PowerBall numbers
