Using a tunable diode laser spectrometer and the sweep integration technique, we have measured the strengths and $N2$-broadened half-widths of a few lines in the P-branch of the $\nu 3$ fundamental of $N2O$. The strength measurements at 297K are consistent with the value $1198cm-2$ atm for the strength of the $\nu 3$-fundamental and $1338cm-2atm-1$ for the combined strength of the fundamental and the ``hot bands”. Our line width data are in excellent agreement with the recently reported FTS data of Lacome et $al1$.
