iam not going to setup anyway. iam curious to know whether the fringes will have good contrast?. considering the pulse is transform limited and have broad spectrum, different spectrum will interefere.

i would expect too. i just want to know how will be the fringe looks like also how possible complication to attain this

what will happen if two one femtosecond(1 fs) laser pulse interferes?

sorry for late reply. The rayleigh range is around 3 m. The wavelength is 1064 nm and beam waist radius is 1 mm.

Yes laser beams are collimated. What i would like to achieve is as shown in figure. After the lens i should get a collimated beam as well. I dont have a data sheet for beam splitter. Beam splitter is a DOE (Diffractive optical element) which will split the incoming beam into two beam of equal...

i want the beam to be have the collimated (Parallel as well as without divergence) for atleast 500 mm after the lens. i have tried the setup in zemax but the beam after certain distance is getting focused and then getting diverged as expected for gaussian beam. on the detector will get a two...

hey. The incoming beam is a laser beam having guassian intensity distribution. Thats why i have mentioned guassian beam, sorry for the confusion. Beam splitter will split the beam in to two beams of equal intensities.

Hi, i would like to design a optics in zemax for collimation of guassian beam. The collimation is to be done for the beam for off axis rays. Attached the foto of what i would like to achieve.
