Coherent, based in Santa Clara, California, has unveiled a series of yellow 561nm lasers that produce high power and efficiency.
The Sapphire 561 is an optically pumped semiconductor laser (OPSL) that offers a choice of 50MW, 75MW, 100MW or 150MW of output power in a high-quality beam with good noise characteristics.
In addition, the high efficiency of Coherent's OPSL technology results in four times better electrical efficiency and lower heat dissipation than products based on legacy Nd:YAG technology.
These Sapphire 561 lasers share the same compact form factor (125mm x 70mm x 34mm or 4.9in x 2.8in x 1.3in) as low-power Coherent Sapphire 488 lasers.
Additionally, all other interface and operating characteristics of the Sapphire 561 are identical with the 488nm-wavelength product, which simplifies the integration of this new wavelength into existing applications.
Furthermore, according to the company, the Sapphire 561 utilises the same proven architecture, supply chain and manufacturing technology as the high-volume, economical Sapphire 488 line.
The combination of performance, price, reliability and size make these Sapphire 561 lasers well suited for a range of applications in the life sciences.
For example, their high power allows faster throughput and improved signal-to-noise ratio in flow cytometry and also enables higher frame rates or reduced exposure times in confocal microscopy.
The company claims that the 561nm wavelength is also well matched to the needs of emerging applications in proteomics and genomics.
