Coherent has brought out a range of yellow (561nm) lasers that it claims produces higher power and offers greater efficiency than anything previously available at this wavelength.
The Sapphire 561 is an optically pumped semiconductor laser (OPSL) that offers a choice of 50, 75, 100 or 150mW of output power in a high-quality (TEM00,M <1.1) beam with excellent noise characteristics (rms noise <0.25 per cent from 20Hz to 2MHz).
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.
The Sapphire 561 laser shares the same compact form factor (125 x 70 x 34mm or 4.9 x 2.8 x 1.3in) as low power Coherent Sapphire 488 lasers.
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.
The Sapphire 561 utilises the same proven architecture, supply chain and manufacturing technology as the high volume, economical Sapphire 488 line.
The Sapphire 561 laser is suited for a range of life-science applications.
For example, its 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 561nm wavelength is also suitable for the needs of emerging applications in proteomics and genomics.
