Thermal lens correction of a diode-pumped Nd:YAG laser of high TEM_00 power by an adjustable-curvature mirror

Abstract: Highly efficient TEM(00)-mode laser power of 11.5 W was obtained by the diode-array side pumping of a Nd:YAG rod. We maintained efficient laser operation at all pump powers by correcting for the changing thermal lens with an adjustable-curvature mirror.

“…A more straightforward and less expensive approach could be by use of a pressure-tuned high-finesse mirror to achieve the desired radius for operation. 47 A high detection sensitivity along with a high resolution brings us precious opportunities to explore new phenomena that are otherwise hidden from us. An ongoing collaboration between JILA and MIT (R. W. Field's group) is to utilize the available sensitivity and resolution of our spectrometer to search for the predicted permutation splitting associated with exchange of the hydrogen atoms when their vibrational amplitudes become significantly large in the high-order overtone band (5 3 ) of 13 C 2 H 2 .…”

“…Moreover there is another type of aberrations named thermo-optical (dynamic or pump-shot) aberrations. These arise during the strong heat generation within the optical pumping [1][2][3][4]. At high intensities, those effects can be amplified by the nonlinear response of the interaction.…”

“…Both static aberrations and thermally induced optical distortions in the active medium are key issues that have to be overcome when laser efficiency needs to be optimized. Some authors used wavefront sensing techniques [3][4][5][6][7], although alternative methods have also been reported: random phase plates, spatial and temporal coherence reduction, shearing interferometry, or phase-retrieval methods [8][9][10][11][12][13].…”

“…Since the calculation of thermal lensing in the beam splitter has difficulty of axi-asymmetric temperature distribution, we took this effect into the simulation by assuming different thermal lensing between both arms. No compensative technique for wave-front distortion [19,20,21] was considered in this calculation. Figure 3 shows the results of the shot noise sensitivity calculated by using the FFT simulation.…”
