This data came from an investigation of an experimental laser at
Bellcore. It was a tunable laser, in the sense that both its
wavelength and power output were controllable.
Usage
data(laser)
Format
A data frame with observations on the variables If and
Ir (the currents applied to the front and rear of the laser),
and power and lambda (the output power and
wavelength).
Details
Rotation helped the experimental physicists to characterize the
laser, which turned out not to be a very good one, due to its
unstable operating region.
This data initially came to the statistics research group when
Janette Cooper asked Paul Tukey to help her analyze the data she had
collected to describe the laser.
