Simulated Design and Characterization of an Efficient Nd:YAG based Solar Pumped Single Mode Laser

Abstract

Abstract

As the current solar pumped lasers have shown to yield a very low efficiency, this research explores the possibility of a simulated design which can be more efficient in converting solar energy into optical power. This paper presents the software design of a Neodymium Doped Yttrium Aluminum Garnet (Nd^3+:Y₃ Al₅ O₁₂) Laser using LASCAD and also presents the characterization of the design using a theoretical mathematical model. Overall, results of output power versus rod length and cavity length were compared to yield the optimum results. Side pumping method was used to pump the Laser. A high output of 102.3 W was achieved by a Laser rod of 25 mm length and 3 mm diameter. A high slope efficiency of 28.14% was also achieved, which is higher than previously recorded values. A low threshold pump power of 36.4 W which is also less than the previous record is used in the design and all along a single mode profile was maintained.
