We report on a CW single-frequency dye laser with a 1-W threshold power. Output power of the laser working on the Rhodamine 19 dye was 100 mW out of 2.4 W of the argon ion pump. Smooth frequency scanning in a 20-GHz region with up to 20-GHz/s rate was implemented in a linear dye laser cavity. A special resonator auto-adjustment system with internal reference features the short-term radiation linewidth down to 3 MHz/s and long-term stability level of 150 MHz/hour without any external frequency stabilization systems. Explained are arrangements of original execution units included into the laser control system. The control system's features are discussed.
