  Monitoring photon quadratures and free masses are useful tools to detect
small disturbances such as gravitational waves.Here we report a large class of
states for photon quadratures and free masses potentially useful for this
purpose: (1)'generic coherent states' (GCS) of photons, whose width is
independent of time and uncertainty product $\sigma (x) \sigma (p) $ is
arbitrarily large (a generalization of the minimum uncertainty Schr\"odinger
coherent states and (2) `squeezed generic contractive states' (SGCS) for
photons and free masses (a generalization of the Yuen states \cite{Yuen}) whose
width decreases with time ,uncertainty product is arbitrarily large, and the
covariance squared $ <\{\Delta \hat{x}, \Delta \hat{p} \}>^2 $ has an arbitrary
value within the allowed range $(0,4 \sigma ^2 (x) \sigma ^2 (p) -1\>)$.
  Dedicated to the 125th birth anniversary of S. N. Bose.
