 \subsection{LASER}  % -----------------------------------------------------------------------------

 

-% TODO: add reference to MaimanTheodore.000 (ruby laser)

+Light Amplified by Stimulated Emission of Radiation (LASER) light sources are absolutely crucial

+components of the modern MR-CMDS instrument.  %

+The first laser was built in 1960 by \textcite{MaimanTheodore1960a}, and pulsed lasers were

+invented soon after [CITE].  %

+Today, ultrafast light sources are relatively cheap and reliable.  %

+Our SpectraPhysics ``Tsunami'' oscillator uses passive Kerr-lens mode-locking to generate $\sim$35

+fs seed pulses at $\sim$80 MHz (one pulse every 12.5 nanoseconds). \cite{Tsunami}  %

+This seed is split and fed into two 1 KHz amplifiers, a picosecond ``Spitfire Ace''

+\cite{SpitfireAce} and a femtosecond ``Spitfire Pro'' \cite{SpitfirePro}.  %

+These amplifiers each output several watts of ultrafast pulses at 1 KHz (one pulse per

+millisecond).  %

 

 \subsection{Optical parametric amplifiers}  % -----------------------------------------------------

 

+Optical Parametric Amplifiers (OPAs) are arguably the most crucial component of modern MR-CMDS, as

+they provide the frequency tunable light sources that we require. \cite{CerulloGiulio2003a}  %

+OPAs provide tunability through three-wave sum and difference frequency generation processes.  %

+``Fundamental'' tunability is achieved by splitting the 800 nm photons into two lower energy

+photons, with a splitting ratio determined by motorized optics.  %

+These split photons are called ``signal'' and ``idler'', with signal being the higher energy and

+idler the lower energy photon.  %

+

+% TODO: paragraph about phase matching conditions and polarization

+

+Signal and idler are then either used directly, or amplified through sum or difference frequency

+processes to provide broadband tuneability.  %

+All available optical processes for the TOPAS-C OPAs \cite{TOPAS-C} used on the femtosecond table

+are shown in \autoref{spc:fig:power_curves}.  %

+

+On the picosecond table we have three separate kinds of OPAs, including one TOPAS-800

+\cite{TOPAS-800} and two OPA-800 models that have been modified with precision micro control

+\cite{PMC} servo motors to provide automated tunability.  %
