We report the production of an extremely cold lithium plasma by optical-field-induced ionization. Such a cold plasma was realized by irradiating a 0.5-ps KrF laser focused into a singly-ionized lithium plasma at an intensity of 10{sup 17} W cm{sup -2}. An average electron temperature of less than 1 eV was estimated by measuring the intensity ratio of the Lyman series line emission in a hydrogen-like lithium plasma. The time history of the Lyman-{alpha} laser (13.5 nm) in a lithium plasma strongly ensures the production of an extremely cold plasma.
