  With the successes of the Laser Interferometer Gravitational-wave
Observatory, we anticipate increased interest in working with squeezed states
in the undergraduate and graduate quantum-mechanics classroom. Because
squeezed-coherent states are minimum uncertainty states, their wavefunctions in
position and momentum space must be Gaussians. But this result is rarely
discussed in treatments of squeezed states in quantum textbooks or quantum
optics textbooks. In this work, we show three different ways to construct the
wavefunction for squeezed-coherent states: (i) a differential equation-based
approach; (ii) an approach that uses an expansion in terms of the
simple-harmonic oscillator wavefunctions; and (iii) a fully operator-based
approach. We do this to illustrate that the concept of the wavefunction can be
introduced no matter what methodology an instructor wishes to use. We hope that
working with the wavefunction will help demystify the concept of a
squeezed-coherent state.
