“…The same group also observed spectral broadening in a Nd:YVO 4 /BaWO 4 laser [10], in which the fundamental spectrum broadened from 0.2 nm at the Raman threshold to 1.05 nm at maximum pump power, whilst the Stokes spectrum broadened from 0.15 nm to 0.5 nm. Lisinetskii et al [11] observed that the fundamental field in their Nd:KGd(WO 4 ) 2 /KGd(WO 4 ) 2 laser broadened from 5 cm −1 to 24 cm −1 (0.6 nm to 2.7 nm) while in an intracavity VECSEL/diamond Raman laser, broadening and complex spectral structure were also observed [12]. However, despite these numerous observations of spectral broadening in intracavity Raman lasers, to the best of the authors' knowledge, no detailed investigation of this phenomenon has been undertaken prior to the study reported in this paper, and here we provide important new insight for selection of Raman gain media.…”

Spectral broadening of the fundamental field in intracavity Raman lasers is investigated. The mechanism for the spectral broadening is discussed and the effect is compared in two lasers using Raman crystals with different Raman linewidths. The impact of the spectral broadening on the effective Raman gain is analyzed, and the use of etalons to limit the fundamental spectral width is explored. It was found that an improvement in output power could be obtained by using etalons to limit the fundamental spectrum to a single narrow peak. 9810-9818 (2012). 20. J. J.

“…2 and 6 are for the following parameters: geff1=26 cm/GW, geff2=8 cm/GW, ksp1=3×10 -3 and ksp2=10 -8 . These effective gain values indicate that the "Raman gain reduction factors" [19] are 0.6 and 0.2 for the 1st and the 2nd Stokes, assuming Raman gain values at 532 nm and 573 nm of ~40 and 39 cm/GW, correspondingly [12]. Higher gain reduction factor for the Raman gain at 573 nm could be due to broader linewidth.…”

Abstract-We report a compact and efficient picosecond diamond Raman laser at 573 nm wavelength. The laser consists of a 0.5 mm thick single-crystal synthetic diamond coated to form a plane-plane laser resonator, and pumped at 532 nm by a frequency-doubled Q-switched microchip laser system. The pump delivers 85 ps pulses at 100 kHz repetition rate at a maximum average power of ~500 mW. We demonstrate 1st Stokes emission from the diamond Raman laser with maximum power of 175 mW, corresponding to a conversion efficiency of 47% and a pulse duration of 71 ps. Substantial pulse shortening is obtained by proper adjustment of the pump spot diameter on the diamond sample. A minimum pulse duration of 39 ps is reported for a conversion efficiency of 36% and 150 mW output power. The simplicity of the architecture makes the system highly appealing as a yellow picosecond laser source.

“…4, means it can be used for a range of wavelengths that other materials cannot compete with. Recent work from the University of Strathclyde has reported that when used in conjunction with frequency doubling and tunable semiconductor sources broad ranges of wavelengths can be produced from a single solid state system [5].…”

Diamond is a material made famous by its rarity, beauty and hardness. Historically, this led to its use almost exclusively in jewellery, yet over the last two decades an increasing number of industrial applications have been developed utilising specifically engineered, volume produced, synthetic diamond. Due to its range of extreme properties it has offered access to applications that were previously not viable. This has been particularly true in the optical applications of microwave powered chemical vapour deposition (MW-CVD) diamond, where, in the last few years, diamond parts have been shown to offer significant improvements over incumbent material solutions.
