The production of cw VUV coherent radiation by four-wave sum frequency generation in Sr vapor is reported. Significant enhancement of the nonlinearity at the output frequency is obtained upon application of large (∼50 kG) magnetic fields. Total power of 10−11 W (∼107 photons/sec) at 1700 Å in a bandwidth of approximately 6 GHz for input powers of less than 1 W was obtained.
