Electron Temperature in a Laser-heated Plasma

Nature volume 204, page 670 (14 November 1964) | Download Citation



WHEN a high-power laser beam is focused on to a material target, a small inertially confined plasma is generated near the target surface. Theoretical work by Basov and Krokhin1,2, verified by Dawson3, suggests that very hot plasmas (107 °K) can ultimately be produced in this way. A spectroscopic investigation of plasmas generated by a small Q-switched ruby laser has already been reported4. Further experiments have now been carried out using a larger Q-switched neodymium glass laser, and an estimate of the electron temperature attained in a carbon plasma is reported in this communication. Other results will be described in detail elsewhere.
