Coherent Launches Long-life Fiber-Pigtailed OBIS Lasers

Coherent Inc has expanded its OBIS family of plug-and-play smart laser modules with a new fiber-pigtailed (FP) option at several wavelengths (e.g. 405 nm, 488 nm, 640 nm). Specifically, these OBIS FP lasers are offered with 1 meter of single-mode, polarization preserving fiber, terminating in a standard FC/APC connector, thus simplifying their integration into OEM instruments. In addition to the inherent ease of use advantages of this compact, self-contained laser platform, these new OBIS FP lasers offer low noise and can be directly modulated.
lasers achieve low noise and exceptional output stability due to two factors. The first is an output beam with the industry’s lowest beam drift to maintain efficient coupling. Second is the use of telecom-type architecture and methods, such as laser welding, to yield drift-free opto-mechanical coupling. OBIS FP lasers also deliver longer lifetimes because they successfully address the main cause of failure in lasers coupled to single mode fibers ? namely facet damage due to the high power density at the fiber facets. OBIS FP lasers use a proprietary design securing a four times longer lifetime than conventional fiber designs which is particularly important for shorter wavelengths such as 405 nm. ##IMAGE_1_R##

Applications for OBIS FP lasers span life sciences, metrology and inspection, where fiber delivery is commonly utilized for miniaturization or other benefits. Specific examples in life sciences include several fluorescence-based techniques such as flow cytometry, confocal microscopy and array readers for drug discovery. Moreover, the wavelength scalability of the OBIS platform enables optimum excitation of target fluorophores.
