Experiments have shown that when a clean tungsten surface is heated by laser irradiation using a focused ruby laser, the rate of evaporation of tungsten from the surface is similar to that obtained by more conventional surface-heating methods. The following experimental data relates the observed temperature change as a function of laser amplitude. Fit a first-order polynomial to these data.

Laser Pulse amplitude:	0.7	0.9	1.1	1.2	1.5	1.7	1.9	2	2.1
Surface temperature (degrees C):	630	740	700	745	1120	1205	1510	1530	1520
