RESUMO
We demonstrate a continuous-wave deuterium Raman laser that generates more than 160 mW of Stokes output power despite severe thermal effects. This output power represents nearly an order-of-magnitude increase over any previously reported continuous-wave Raman laser and is the first such system to our knowledge that uses deuterium gas as the Raman medium. The high output power is achieved through careful consideration of the electronic feedback design, frequency actuators, and pump-laser intensity noise.
RESUMO
A highly efficient 1.3-microm molecular iodine Raman laser is demonstrated. Multiwavelength output powers of 600 mW and photon-conversion efficiencies of 78% are demonstrated for a 532-nm pump source. Single-wavelength output powers of 480 mW and photon-conversion efficiencies of 67% are also realized. A simple thermal lensing model is used to optimize the pump and Stokes mode sizes.
