…Static gas lifetime of a standard PLD laser filled with 248 nm premix gas.
The low pulse count translates into a lifetime for the laser
tube of about 10 years and also into long exchange cycles for
the resonator optics of 3-5 years, as indicated in figure 1.
As the excimer laser

…14 million laser pulses with the same gas fill.
The laser gas consumed for the gas lifetime of 14 million laser pulses amounts to only 16 liters. Moreover, a
factor of two reduction of gas consumption is achieved by
means of consecutive on-the-fly premix gas injections during laser

…photons and fluorine gas -

albeit pre-mixed in trace amounts.
In the early days of PRK and LASIK,
surgeons would have many questions
about the laser itself; how many shots
will it give for each gas fill, how easy is
it to refill the gas inside the laser tube,
what…
