Kevin,
Yes, you can think of a MOSFET switching transistor as a kind of solid state thyratron.
I once used miniature thyratrons made by EG&G to apply 100 amp pulses to GaAs laser diodes. The pulses were very brief (20-50 nsec) and had ultra-fast risetimes. The power supply was two 67.5 volt batteries in series.
Back in the last century I wrote an article about this high-current laser pulser for Ham Radio magazine ("High Power Injection Lasers," September 1971, 28-33).
The commercial name of this thyratron was Krytron. The Krytron was developed to initiate the detonation of a certain kind of mass destruction device. This application caused its export outside the US to be banned.
The device is the size of the end of your thumb and contains a radioactive isotope.
