As we know, chirped pulse amplification, a kind of time-spectrum encoding, has scaled the femto-second pulse to several
petawatts. Here we report a novel technology, we call it spectrum-polarization encoding (SPE) for broadband pulse, which is
realized by inducing some optical rotatory dispersion (ORD), and decoded by compensating ORD. By the aid of optical polarizers,
SPE can induce spectral polarization-dependent loss and gain. Accordingly, SPE can not only work as optical filters by controlling
polarization-dependent transmission to tune central wavelength or bandwidth, as a tunning component inside laser oscillator to
tune output wavelength, but also be used in ultrafast light pulse shaping. Our results show SPE can help a Ti: S regenerative or
multi-pass amplifier to boost an 800 nm pulse up to mJ level with a bandwidth to support few-cycle pulse duration. SPE is entirely
passive thus very simple to be designed and aligned.
