2W 1064nm Demo

Finally got the new 1064nm laser video up on YouTube. It ran a little long so I had to re-edit it for time.

Nice!

Nice. I love the trivia.

Is that excited by an 808 LD bar ? How many watts on the pump?

Actually the system is a linear, end pumped laser system with a <4W pump diode. YVO4/1064nm generation is surprisingly efficient as the absorption spectrum of YVO is greater than YAG plus the cavity design adds to the efficiency if the pump diode is properly collimated and focused. You don't just shoot a beam of 808nm into the crystal. It's a maximization issue relating to beam waist within the YVO active area (due to a hemispherical OC) versus absorption by nonactive regions that sets the pump diode cross section entering the YVO and the depth of focus.

WOW -- still 50%+ efficiency !!! Nice laser. You get to play with all the toys

Evolution is lie.
