• We present the generation of pulsed squeezed light at telecommunication wavelength of 1.535 μm via single-pass parametric amplification in a periodically poled MgO-doped lithium niobate waveguide using a novel collinear configuration. The quadrature-amplitude of squeezed light is measured in time domain. The classical parametric deamplification of $-3.2$ dB and quadrature squeezing of $-1.5$ dB are observed. The maximum classical parametric amplification of 19.3 dB is obtained at pump average power of 0.47 mW, taking advantage of the tight confinement in a waveguide and high peak power of the pulsed light.
