The mode-matching lenses were adjusted to produce a beam diameter of approximately 280 um, 76 mm away from the
input window of the power amplifier.  The two-lens solution, using a nominal -50 mm and 80 mm focal length lenses,
is very sensitive to the position of the second lens.

    The power amplifier was turned on, without any incident beam from the front end laser, without anything
untoward noticed.  A low power beam from the front end laser was put into the amplifier and an amplified beam
was observed coming out.  There is still some alignment work to be done to see what the output power of the
amplifier will be, in addition to mode matching and alignment to take its output through the rest of the optical
train.

    The amplifier was operated without the shutter, as we do not have the parts in hand to complete fabrication
of the shutter.
