MAG/HSRL/M1 - Laser diode shutoff

The transmitted_energy dropped from normal values of ~10,000 J to ~800 J and the 
beta_a_backscatter profiles were incorrect. This continued until 8/20/2013 when the values 
returned to expected values. The beta_a_backscatter profile were in "In Port" mode on 8/22/2013. 
With no structure in the return.

The laser diode shut off due to an overheat condition.  It was remedied by a full power 
off and restart.
