We describe laser systems for photoionization, Doppler cooling and quantumstate manipulation of beryllium ions. For photoionization of neutral beryllium,we have developed a continuous-wave 235 nm source obtained by two stages offrequency doubling from a diode laser at 940 nm. The system delivers up to 400mW at 470 nm and 28 mW at 235 nm. For control of the beryllium ion, three laserwavelengths at 313 nm are produced by sum-frequency generation andsecond-harmonic generation from four infrared fiber lasers. Up to 7.2 W at 626nm and 1.9 W at 313 nm are obtained using two pump beams at 1051 and 1551 nm.Intensity fluctuations below 0.5 % per hour (during 8 hours of operation) havebeen measured at a 313 nm power of 1 W. These systems are used to loadberyllium ions into a segmented ion trap.
