  The exclusive production of baryon antibaryon pairs in the collisions of two
quasi-real photons have been studied in different experiments at e+e-
colliders. Results are presented for the processes gamma gamma to proton
antiproton and gamma gamma to lambda antilambda. The cross-section measurements
are compared with the recent analytic calculations based on the quark-diquark
model predictions. Monte Carlo studies have been done to investigate the PEP-N
expectations for the gamma gamma to proton antiproton process.
