Hi DAB, I'm looking for a type of laser that can intersect with another laser to interfere or stop the propagation of the lasers. Is there any way of doing this?
Maybe you are talking about shutter. Basically you have fs laser that acts as shutter, and you have some material, that you shine light into. Ultrafast pulse changes properties of sample ( like Kerr effect) , and you pass light only at that "two wave interaction" point
it acts as On/Off switch by using Kerr effect. basically you will create shutter with ultrashort impulse, and you can "chop" other light source with it, aka shutter
it is only for fs lasers, like Ti:Sa or Yb:KGW, since you need lot of intensity to get Kerr effect into action, it's not about average power, it's about peak intensity
you should look for Pockels cell, or Faraday rotator, you could control it by voltage/current by using polarized light and polarizer. This is best way to control light from laser. But it is controlled by electricity, not by light, so i don't know will fit your purpose
