What kind of pulsed laser do I need for life object or ultra fast events holograms recording?
You would need a pulsed laser providing Single Longitudinal Mode and coherence length not less than several meters. The holographic material suitable for this application is VRP-M. • How does refrigeration of Slavich films and plates affect their lifetime? The practical lifetime of VRP/VRP-M plates and film at 20/25 degrees C and low humidity is more than 5 years. Rolls of film can last even longer reaching greater than 10 years. At +4 degrees C the lifetime for plates and sheet film is around 10 years. The practical lifetime of PFG-01 plates at 20/25 degrees C is around 3 years. At 4 degrees C it is rather more although how much more has not yet been tested. Sheet film behaves similarly to the plates and rolls are again much longer-lived. The practical lifetime of PFG-03M/C plates when stored in plastic boxes at +4 degrees C is till 12 months. Rolls of film at +4 C last more than 1.5 years. PFG-04 practically lasts 24 months at +4C and 12 months at +20 C. Practically the optimum stora
