Multiple Passage

Here we present the results of our study on the feasibility of a multi-pass pumping scheme in solar lasers. A secondary concentrator has been developed to ensure the multiple passage of solar photons through the active medium. When using a multi-pass pumping scheme, an increase of 12.5% in the luminescence spectra of Nd:YAG is observed in the vicinity of the lasing line at a wavelength of 1064 nm

Specific Experiment

With a view to obtain a compact laser jammer, we have conducted the design of solid laser with peak power, designed the light-gathering cavity by means of ZEMAX software and analyzed the heat effect of active medium by means of LAS-CAD software. According to the design result, we operated a specific experiment, thus obtaining the peak power laser with a volume of 0.009m3, a repeated frequency of 1Hz and a single pulse power of 25MW.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
