Coherent Laser Light Sources

OBIS Laser

OBIS is a breakthrough laser platform offering plug-and-play operation with the widest range of wavelengths available. With lasers from 375 nm to 785 nm, an integrated controller and compact packaging, OBIS is the smallest - and smartest - laser platform on the market. Simply plug in the DC source and your laser is operating. Need a different wavelength? Unplug the old and plug in the new. It's as simple as that.

Featuring the same footprint and beam propagation across all OBIS units saves integration costs. With its unique feature set, OBIS answers the need to cover a rapidly expanding range of wavelengths in Life Sciences and other instrumentation applications.

OBIS is a smart design that allows for direct modulation saving costs and complexity of modulators. A full suite of interface options enable simple integration.

Different technologies continue to serve a demand for distinct wavelengths.

OBIS LX: Laser Diode Technology

OBIS LX diode solutions represent the leading industrial design for diode modules. They feature with protection against elecrostatic discharge, thermal management with Thermo-Electric Cooler stabilization and unit‐to‐unit consistent superior spatial beam quality.

OBIS LS: Optically Pumped Semiconductor Laser (OPSL) Technology

OBIS LS solutions use Coherent's proprietary OPSL (Optically Pumped Semiconductor Laser) technology, which offers performance benefits and proven reliability.

Benefit: Superior Low Noise. OPSL offers superior low noise due to the short upper state lifetime of the semiconductor gain medium — it has no green noise problem.

Benefit: Elimination of Limitations on Change of Output Power. OPSL technology uses a thin semiconductor gain medium, which eliminates such limitations as found with other conventional DPSS lasers. It also eliminates the use of thermal lensing, which allows one to vary the output power to meet application needs while taking advantage of invariant beam parameters.

Reliability. OPSL technology is well proven over several years with more than twenty thousand installed lasers in both laboratory and rugged field applications. Its superior reliability ensures consistent uptime and the lowest cost of ownership in demanding industrial and research applications.
