Abstract
Efficient soft x-ray lasing was achieved by using plasma waveguide to confine the pump beam. With a 9-mm-long pure krypton plasma waveguide prepared by using the axicon-ignitor-heater scheme, lasing at 32.8 nm is enhanced by 400 folds. An output level of 8×1010 photon/shot is reached at an energy conversion efficiency of 2×10-6. Seeding the laser with high-harmonic generation yields small divergence, high coherence, and controlled polarization. Application in digital holographic microscopy was demonstrated.
