| Summary: | Narrow linewidth operation of several lasers and optical amplifiers is demonstrated. Investigation of linewidth broadening in long pulse alexandrite lasers and a solution to correct the effect is described. A narrow linewidth, tunable, continuous wave device operating in the green spectral range was built using double clad single mode fiber technology, it provides 1.74 W at the fundamental wavelength, and 110 mW at the second harmonic wavelength. Its suitability for spectroscopy applications is proven by performing absorption spectroscopy on ¹²⁷I₂ and ¹²⁹I₂. Finally, a new method to generate narrow linewidth high energy pulses in a very rugged setup is demonstrated. A multistage fiber amplifier that amplifies pulses to peak powers in excess of 100 W was built. These were then amplified to more than 1 MW peak power in a flashlamp pumped Nd:YAG rod. |
