Tunable and frequency-stabilized diode laser using temperature-dependent energy pooling fluorescence

Abstract

We have demonstrated a robust method of tuning and stabilizing a diode laser frequency to the fluorescence peaks of the energy pooling occurred at thermal cesium vapor-glass interface. This technique is based on temperature-dependent shift of the two off-core fluorescence peaks caused by 6P3∕2+6P3∕2→7P(3∕2,1∕2)∕8S1∕2+6S1∕2 energy pooling collisions. We achieved laser linewidth of 1.1MHz and continuous tunability over ±200–600MHz within a temperature range of 360–420K by applying the wavelength modulation technology. Tunable frequency locking in such a wide range was constructed inexpensively with low laser power. It can also be extended to other wavelengths by using different atomic species.

Laser offset-frequency locking against energy pooling fluorescence in thermal caesium vapour

Liantuan Xiao, Tao Huang, Lirong Wang +2 more

We have shown that energy pooling fluorescence lock provides an effective method for stabilizing a diode laser to a broad, stable atomic reference. We achieved typically a stable lock with a laser linewidth of 1.1 MHz and continuous tunability of ?600 MHz, against the two off-centre peaks fluorescence of 7P(3/2, 1/2) ? 6S1/2 caused by 6P3/2 + 6P3/2 ? 7P(3/2, 1/2) + 6S1/2 energy pooling collisions in thermal caesium vapour.

Frequency-stabilized diode laser with the Zeeman shift in an atomic vapor

Kristan L. Corwin, Zheng‐Tian Lu, Carter F. Hand +2 more

We demonstrate a robust method of stabilizing a diode laser frequency to an atomic transition. This technique employs the Zeeman shift to generate an antisymmetric signal about a Doppler-broadened atomic resonance, and therefore offers a large recapture range as well as high stability. The frequency of a 780-nm diode laser, stabilized to such a signal in Rb, drifted less than 0.5 MHz peak-peak (1 part in 10(9)) in 38 h. This tunable frequency lock can be constructed inexpensively, requires little laser power, rarely loses lock, and can be extended to other wavelengths by use of different atomic species.

Temperature-insensitive laser frequency stabilization with magnetic tuning

Lucas Willis, M. J. Lim

We have implemented a tunable laser frequency lock with a wide recapture range and low sensitivity to temperature fluctuation, based on electronically power-normalized Doppler-broadened absorption spectra. The method requires no frequency modulation. A distributed-feedback diode laser locked to this system exhibits submegahertz stability over many hours. It has been used to magneto-optically trap rubidium atoms for a full day.

Laser frequency stabilization and shifting by using modulation transfer spectroscopy

Bing Cheng, Zhaoying Wang, Bin Wu +4 more

The stabilizing and shifting of laser frequency are very important for the interaction between the laser and atoms. The modulation transfer spectroscopy for the 87 Rb atom with D2 line transition F = 2 → F′ = 3 is used for stabilizing and shifting the frequency of the external cavity grating feedback diode laser. The resonant phase modulator with electro—optical effect is used to generate frequency sideband to lock the laser frequency. In the locking scheme, circularly polarized pump- and probe-beams are used. By optimizing the temperature of the vapor, the pump- and probe-beam intensity, the laser linewidth of 280 kHz is obtained. Furthermore, the magnetic field generated by a solenoid is added into the system. Therefore the system can achieve the frequency locking at any point in a range of hundreds of megahertz frequency shifting with very low power loss.

Frequency-locked tunable LD laser with a broad bandwidth

常宏, 武海斌, 谢常德 +1 more

Using lock-in amplifer and proportional, integral, and derivative (PID) electric circuit, the frequency of diode laser is stabilized on a highly mechanical stable Fabry-Perot (FP) cavity transmission peak. When the frequency locking system is on, the frequency tunable range of the laser is about 4GHz around the D1 transition of Rb. The laser frequency tuning is implemented by scanning the FP cavity length. The fluctuation of frequency of the output laser is less than 1MHz, and the drift of the center frequency is less than 1.5MHz in 1.5min. This system has great potential of the application in the experimental investigation of the interaction between light and atoms, especially, for the case of far off the atomic resonance.

Frequency stabilized diode laser with variable linewidth at a wavelength of 4047 nm

Benjamin Rein, Thomas Walther

We report on a frequency stabilized laser system with a variable linewidth at a wavelength of 404.7 nm used as an incoherent repump on the 6P30↔7S31 transition in mercury. By directly modulating the laser diode current with Gaussian white noise, the laser linewidth can be broadened up to 68 MHz. A Doppler-free dichroic atomic vapor laser lock spectroscopy provides an error signal suitable for frequency stabilization even for the broadened laser. Without the need of an acousto-optic modulator for the linewidth tuning or lock-in technique for frequency stabilization, this laser system provides an inexpensive approach for an incoherent and highly efficient repumper in atomic experiments.
