“…To achieve required yellow sources, a variety of approaches have been explored in recent years. These include intracavity sum-frequency mixing in a self-Raman Nd:YVO 4 laser at 559 [5], 553, and 561 nm emission by frequency doubling the 1106 and 1123 nm lines of Nd:YAG [6], Nd:YAG 589 nm yellow source based on sum-frequency mixing of 1064 and 1319 nm laser lines [7,8], or sum-frequency mixing of 1053 and 1338 nm laser lines [9]. Stimulated Raman scattering (SRS) is an attractive method of frequency conversion based on a third order nonlinear optical process.…”

We present a simple laser architecture to obtain continuous-wave (CW) true yellow light sources at the 579 nm. A 806 nm diode-pumped a Nd:YLF crystal emitting at 1047 nm with intracavity Raman shifting by SrWO 4 crystal at 1158 nm. Intracavity frequency-doubling at 1158 nm was then realized in a LiB3O5 (LBO) crystal to reach the yellow-orange radiation. To realize CW yellow radiation, high-Q resonator is applied to resonate two optical fields (i.e. the fundamental, and the first Stokes) by design high performance mirrors and partly sharing linear resonator. The stimulated Raman scattering (SRS) resonator losses is effectively reduced. We obtained a CW output power up to 889 mW at 579 nm with an incident pump power of 15.3 W at 806 nm, corresponding to an optical conversion efficiency of 5.8% with respect to the incident pump power

“…Finally these sources are particularly suited for external cavity frequency doubling and could lead to a set of deep UV wavelengths ranging from 266 nm to 280 nm. For the latter application, wavelength stability as discussed in [5] is a key factor.…”

Since the first introduction of DPSS lasers at 561 nm in 2004, the power level required by some biotechnical applications has always increased. Oxxius has contributed to fulfill the demand thanks to the introduction of the SLIM-561 100mW in 2008 and of the SLIM-561 200mW and 300mW in 2009. More recently, new dyes or nano-dots have required shorter wavelengths (such as 553 nm) and new applications such as Laser Doppler Velocimetry requiring both high power and single frequency operation have appeared.In this presentation, we demonstrate how to further increase the power. 553nm and 561 nm emission are obtained by frequency doubling the 1106 nm and 1123 nm lines of Nd:YAG. The latter transitions are significantly weaker than the 1064 nm line. As a consequence, any loss in the cavity significantly increases the laser threshold. Because of the perfect alignment of the crystal interfaces and the low divergence of the intracavity beam, monolithic cavities demonstrate significantly reduced round-trip losses compared to standard cavities. Consequently, laser threshold can be dramatically reduced and the nonlinear loss, responsible for the visible emission, can easily dominate the linear losses. We have taken standard monolithic cavities of our commercial SLIM-561 products and have increased the pumping power up to 2.8 W. Yellow and Yellow-green powers have not shown any sign of saturation and 0.5 W could be achieved at both wavelengths. This results in a record 18% pump to signal optical efficiency. We have checked that the emission remained single frequency whatever the pumping power.

“…Therefore, a slight tilt in the end face of the fiber or the cavity mirror will rapidly increase the loss of the laser [41]. Besides, in the resonant cavity, the end reflector is sensitive to the smoothness of the fiber end face, and subtle defects can cause damage to the instrument [42], [43]. Therefore, the memristors cannot be introduced into the laser system during the theoretical analysis period.…”

In this paper, a new chaotic system is proposed by adding a magnetron memristor to an erbium-doped fiber laser circuit, and its dynamical characteristics are analyzed. A special periodic coexistence attractor phenomenon was discovered during the analysis, which affects the dynamical characteristics of the system by changing the time parameters of the AC power supply and it is controllable. Finally, the chaotic system is implemented by constructing an equivalent analog circuit. Theoretical analysis and simulation results show that the new erbium-doped fiber laser chaotic system has good dynamical characteristics and it is easy to implement. Meanwhile, the rich dynamical characteristics of the system provide a basis for its application in image encryption and other fields.
