A hard-core flashlamp (HCF) which has a coaxial geometry and an array of inverse pinches was evaluated for blue-green laser excitation. The short pulses ({lt}0.5{mu}s) surface discharges were produced across the core insulator of teflon and alumina. The spectral irradiance of the HCF depends on argon fill gas pressure and the core insulating material. The maximum radiative output of the HCF lies in the region of 340--400 nm (the absorption band of LD 490). An LD490 dye laser pumped by a HCF prototype device had an output of 0.9mJ with a pulse width of 0.5{mu}{ital s} (FWHM).
