... physical effects and making the frequency control non-robust at best. To obtain an absolute frequency reference to lock the pump laser against, a photoacoustic cell (see Figure 5) which uses the FIR Laser vibrational pump transition in methanol,2 was designed and tested. · Methanol @ ~0.5 Torr · Intra ...
