Meeting The Challenge
• Efficient generation of Relativistic Protons i.e.61GeV, for efficient neutron generation.
• It means I~1023W/cm2
• Could we do it with laser, knowing that the laser
is extremly inefficient?

Fiber vs. Bulk lasers
•
High Gain fiber amplifiers allow ~
50% total plug-to-optical output
efficiency reachable
•
Single mode fiber amplifier have
reached 10kW optical power because
the large surface area volume ratio.
large bandwidth (100fs)
High rep. rate 10kHz>1/tf, highly
desirable for diode stability, lifetime
and system noise
Excellent beam quality
Efficient, diode-pumped operation
Pigtail pumping vs stacks
They can be mass-produced at low
cost.
