High-performance frequency stabilization of ultraviolet diode lasers by using dichroic atomic vapor spectroscopy and transfer cavity*

Abstract: We develop a high-performance ultraviolet (UV) frequency stabilization technique implemented directly on UV diode lasers by combining the dichroic atomic vapor laser lock and the resonant transfer cavity lock. As an example, we demonstrate a stable locking with measured frequency standard deviations of approximately 200 kHz and 300 kHz for 399 nm and 370 nm diode lasers in 20 min. We achieve a long-term frequency drift of no more than 1 MHz for the target 370 nm laser within an hour, which is further verified … Show more

“…Single-frequency Nd:YAG laser has a wide range of applications, as optical metrology, high-resolution spectroscopy, coherent detection, [1][2][3][4][5][6][7][8] and especially Fouriertelescopy (FT). [9][10][11][12][13][14][15][16][17][18] To obtain a single-frequency laser, three problems need to be solved, including single longitudinal mode selection, single transverse mode selection, and energy enhancement.…”

“…Pound-Drever-Hall (PDH) technique, as a powerful and elegant locking method, has been widely adopted to achieve a narrow-linewidth and low-noise laser by stabilizing the frequency of the laser to a high-finesse optical cavity. [1][2][3][4][5][6] Precision metrology, [7][8][9][10][11] atomic [12,13] and molecular [14][15][16] manipulations have directly benefited from the resulting improvement in laser stability. For example, interferometric measurements such as the search for gravitational waves critically depend on the availability of narrow-linewidth laser systems with extremely low frequency and amplitude noise.…”
