Here is the 589 yellow laser review by xm360, i know many people are pursuing high output lasers, but a 5mw yellow laser is much more beautiful than a 5w 450nm blue laser, the bright blue laser beam may let you scared, but this yellow laser just let you feel warm.

We demonstrate high-power high-efficiency cavity-enhanced second harmonic generation of an in-house built ultra-high spectral density (SBS-suppressed) 1178nm narrowband Raman fibre amplifier. Up to 14.5W 589nm CW emission is achieved with linewidth Δν589<7MHz in a diffraction-limited beam, with peak external conversion efficiency of 86%. The inherently high spectral and spatial qualities

A compact frequency-stabilized laser system at 589 nm is demonstrated for sodium laser guide star and sodium lidar. The 589 nm laser based on all-fiber devices was generated by the sum frequency generation (SFG) of the distributed-feedback laser diodes (DFB-LD) seed lasers of 1064 nm and 1319 nm. The absolute frequency was locked to the D2a line by adopting the method of saturated absorption

We demonstrate the cascaded coherent collinear combination of a seed-split triplet of 1178nm high-power narrow-band (sub-1.5MHz) SBS-suppressed CW Raman fibre amplifiers via nested free-space constructive quasi-Mach-Zehnder interferometry, after analysing the combination of the first two amplifiers in detail. Near-unity combination and cascaded-combination efficiencies are obtained at all

The 589 nm laser can effectively stimulate the D 2a line transition of sodium atom in the atmosphere. Because the laser targets are remote and the transition of D 2a line is very narrow, the laser parameters are required to be relatively strict. The accurate value of the laser wavelength is 589.159 nm, the linewidth is less than 3 GHz, and the
