C first row illustrates the nearand far-field patterns that occur when a 27.7 pm tilt (measured peak-peak for the extreme edges of the concave mirror) is put into the cavity without adaptive compensation. The closed loop enhancement of the nearand far-field intensity patterns, is shown in the second row in the figure. In addition to significantly improving the nearand far-field intensity distributions, adaptive resonator techniques can also increase the extracted output power of the laser. The… CONTINUE READING
