Abstract

A simple theoretical model for the calculation of the dependence of filter quantum efficiency versus laser pump power in an atomic Rb vapor laser-excited optical filter is reported. Calculations for Rb filter transitions that can be used to detect the practical and important frequency-doubled Nd lasers are presented. The results of these calculations show the filter's quantum efficiency versus the laser pump power. The required laser pump powers required range from 2.4 to 60 mW/cm/sup 2/ of filter aperture.>

Ultrahigh-resolution, wide-field-of-view optical filter for the detection of frequency-doubled Nd:YAG radiation

T. M. Shay, Yun Chur Chung

We report a simple theoretical model for the calculation of the dependence of filter quantum efficiency versus laser pump power in an atomic Rb vapor laser-excited optical filter. We present the calculations for a 532.4-nm Rb filter that can be used to detect the practical and important frequency-doubled Nd:YAG laser. The results of these calculations show that the filter's quantum efficiency is relatively insensitive to the laser pump power. The laser powers required to pump the filter range from 3.6 to 226 mW per square centimeter of filter aperture.

Experimental demonstration of a diode laser-excited optical filter in atomic Rb vapor

Yun Chur Chung, Thomas M. Shay

A narrow-bandwidth optical filter using diode-laser-pumped atomic Rb vapor has been demonstrated. Excellent rejection of off-resonant laser photons has been achieved. The measured detection bandwidth was 1.18 GHz at the Rb cell temperature of 150 degrees C, which shows a good agreement with the calculated detection bandwidth of 1.02 GHz. The quantum efficiency of the atomic Rb vapor laser-excited optical filter is linearly dependent on the diode laser pumping power.>

Detection of 532-nm frequency-doubled Nd:YAG radiation in an active rubidium atomic resonance filter

Monica L. Minden, Hans W. Bruesselbach

We report the detection of frequéncy-doubled Q-switched Nd:YAG laser radiation at 532.24 nm by an active rubidium atomic resonance filter. The Rb 5p level was populated by using a diode laser operating at 795 nm. The 532-nm laser excited atoms to the 10s level; these decay through p levels to the ground state. Signals were observed at 420/422 nm and 359 nm, corresponding to fluorescence from states 6p and 7p. Fluorescence noise was observed only on the 420/422-nm transition; the 359-nm signal had no detectable noise.

Transmission characteristics of an excited-state Faraday optical filter at 532 nm

Yufeng Peng

In this paper the calculations for a K Faraday filter at 532.33 nm that can be used to detect the practical and important frequency-doubled Nd:YAG laser are presented and discussed. Our model predicts a peak transmission of 50% and an equivalent bandwidth of 4 GHz for the filter operating on the transition in potassium. The theoretical results show the transmission characteristics of the filter are relatively insensitive to the laser pump power and magnetic strength. The laser pump powers required range from 0.8 to .

Theoretical Modeling and Analysis of Blue Laser Characteristics of Continuous-Wave Single-Wavelength Two-Photon Pumped Rb-Vapor Laser

Yanhui Ji, Yang He, Haohua Wan +2 more

Based on an analysis of kinetic processes in the continuous-wave (CW) single-wavelength two-photon pumped Rb-vapor laser (Rb-TPAL), a three-dimensional computational model is established using the rate equation. Based on the application of the model to cavity-enhanced Rb-TPAL [Yuanet al.,Optics Express29, 4858 (2021)], the calculated and measured dependences of the laser power on the pump power show good agreement. We simulate the Rb-TPAL pumped by a high-power CW laser diode and analyze the effects of temperature, vapor cell length, pump waist, vapor cell transmission, and output mirror reflectance on the characteristics of the blue laser. The results suggest that the output power and efficiency of blue laser can be improved by optimizing the above parameters; however, the particles in the$5^{2}\text{D}_{5/2}$level face difficulty to transition to the$6^{2}\text{P}_{3/2}$level, and this limits the further improvement of blue laser efficiency; therefore, an approach is proposed to improve the efficiency of Rb-TPAL. This study can be useful for designing a two-photon pumped alkali metal laser with high-power output.
