In summary, when two lasers meet, their interaction depends on their wavelengths and power levels. If they have the same wavelength and power level, they can cancel each other out at a specific angle. If they have different wavelengths, they will not interact and will continue on their paths. However, lasers with different wavelengths and power levels can combine to form a more powerful beam through laser amplification. Additionally, two lasers can create destructive interference and cancel each other out if they have opposite phases and meet at a specific angle.

WHat happpens when two Lasers meet,is their behavior same as when two Light beams meet that are emitted from a general Electric torch,i want to know what happens
Thanks in advance

Nothing and yes.

But when matter is present at the crossing point, very interesting effects can happen, especially if we're talking about femtosecond pulses meeting in a non-linear crystal (incidently the subject of some of my graduate studies).
 

What happens when two lasers meet?

When two lasers meet, they can either pass through each other or interact with each other depending on their wavelengths and power levels.

Can two lasers cancel each other out?

Yes, two lasers with the same wavelength and power level can cancel each other out when they meet at a specific angle.

What happens if two lasers have different wavelengths?

If two lasers have different wavelengths, they will not interact with each other and will continue on their paths without any change in their properties.

Can two lasers combine to form a more powerful beam?

Yes, two lasers with different wavelengths and power levels can combine to form a more powerful beam. This is known as laser amplification.

Is it possible for two lasers to create destructive interference?

Yes, if two lasers meet at a specific angle and have opposite phases, they can create destructive interference which results in cancellation of the beams.
