Conventional lens-based image relays introduce radial group delay that significantly reduces focal-spot intensity of ultra-broadband short pulses. A direct compensation scheme that can be used with conventional singlet image relays is proposed. The compensation scheme is based on using two negative lenses embedded within an Offner imaging system. The setup allows a single-pass configuration and eliminates the need for polarization switching optics. The performance of this setup is calculated… CONTINUE READING
