“…In order to thoroughly eliminate the influence of the modulation signal on the laser noise and obtain a low-noise single-frequency CW Ti:sapphire laser to satisfy the requirements of quantum information and precise measurement, an etalon made of a birefringent crystal can be adopted in the laser system. With the assistance of the birefringent effect of the crystal, the error signal can be extracted by detecting the polarization state variation of the reflected laser from the etalon and the etalon locking can be implemented by a modulation-free locking system [35].…”

“…In the continuously tunable single-frequency CW Ti: sapphire laser as shown in Figure 6, a BE made by LiNbO 3 crystal was adopted as the mode selector [35]. It was inserted into the laser resonator with its x-axis setting about 2 ~3°r elative to the polarization orientation of the oscillating light and stably locked to an oscillating laser mode by detecting the polarization state of the reflected laser from it.…”

“…These studies paved an effective and feasible reference to develop a low-noise single-frequency CW tunable laser. On this basis, low-noise high-power continuously tunable single-frequency CW Ti:sapphire lasers with intensity noise manipulation [34] and modulation-noisefree [35] were realized respectively. In addition, the continuous laser frequency tuning range obtained with the etalon locking [23], which gave out an ingenious method to realize broadband continuously tunable lasers.…”

All-solid-state single-frequency continuous-wave (CW) lasers have been applied in many fields of scientific research owing to their intrinsic advantages of high beam quality, low noise, narrow linewidth, and high coherence. In atom-based applications, single-frequency lasers should also be continuously tuned to precisely match their wavelengths with the transition lines of the corresponding atoms. Continuous frequency tuning of the laser is mainly achieved by continuously scanning the laser cavity length after the intracavity tuning element etalon is locked to an oscillating laser mode. However, the modulation signals necessary in current etalon locking systems increase the noise of the continuously tunable lasers and in some respects limit their applications in Frontier scientific research. Moreover, the obtained continuous frequency tuning range with the etalon locking technique is restricted by the free spectrum range of the adopted etalon. In this paper, we systematically summarize recent progress of the continuously tunable single-frequency CW lasers based on intracavity locked etalon, including the advanced etalon locking techniques and the tuning range expansion approach. As a result, the low noise and high stable all-solid-state single-frequency CW tunable lasers are successfully developed.

Realization of CW single-frequency tunable Ti:sapphire laser with immunity to the noise of the pump source

All-solid-state continuous-wave (CW) single-frequency tunable Ti:sapphire (Ti:S) laser is an important source in quantum optics and atomic physics. However, intracavity etalon (IE) locking is easily influenced by the intensity noise of the pump source in the low frequency band. In order to address this issue, a differential detector with dual-photodiodes (PDs) is designed and employed in the experiment. Both PDs are used to detect the lights of the pump source and the built Ti:S laser, respectively. As a result, the influence of the intensity noise of the pump source on the stability of the IE locking is successfully eliminated and the IE is stably locked to the oscillating longitudinal-mode of the laser. On this basis, a stable CW single-frequency tunable Ti:S laser is realized. The presented method is beneficial to attain a stable single-frequency tunable laser with immunity to the intensity noise of the pump source.
