Third-harmonic generation and multiphoton ionisation were simultaneously monitored at several pressures in Kr gas following excitation by a strongly focused dye laser, tunable over the range 338 to 350 nm. The results indicate that the multiphoton ionisation signals due to the nf [ l/2] autoionising
## Abstract In this paper, we compare the use of various field approximations of modal fields for gain calculations in erbium‐doped fibers. Our results show that the use of an appropriately chosen rectangular approximation leads to simple analytical expressions for the gain characteristics, and sti
