Laser plus iron target:broad‐band x‐ray source
DOI: 10.1063/1.3070671
By bombarding a thick iron target with a high‐power laser, a broad‐band source of x rays has been produced. The conversion efficiency of 1.06‐micron laser light into x rays is at least 10%, probably 15–20% and possibly 30–40%, according to Philip Mallozzi (Battelle Memorial Institute, Columbus), who announced his results at the Esfahan (Iran) Symposium on Fundamental and Applied Laser Physics in September.
