Snake Creek Lasers, LLC, was founded in 2003 by Dr. David C. Brown, a well-known expert in solid-state lasers. We are located in a modern research and development and manufacturing facility near Friendsville, a part of the beautiful Endless Mountain Region of northeastern Pennsylvania. The company invented and began manufacturing green (532 nm) microlasers (MicroGreenTM and MiniGreenTM) in 2005. Many thousands of devices are currently in operation worldwide and used for pointing, illumination, guidance, and many other applications in the industrial, bio-medical, and military marketplaces. We manufacture in addition a number of standard and custom specialized laser modules that incorporate power supplies, beam expanders, and boresight control.

The Snake Creek Lasers MiniGreen™ Seriesis a diode-pumped solid-state laser packaged in a 9.0 mm diameter, and less than 1 cm3can--the world’s highest power density (mW/cm3) 532nm microchip laser.
Snake Creek’s quest for miniaturization resulted in a mass-producible, alignment-free optical design with near-diffraction limited and high electrical-to-optical efficiency output beam with less than 0.5% residual 1064nm power content; also resulting in a DPSS laser with high-G force tolerance and inherent reliability.
Options include active power-stabilization, high polarization ratio, and screening service to select and identify the optimum condition for narrow or broad line-width operation. Applications for MicroGreen Series include excitation source for bio-fluorescence and Raman spectroscopy, metrology, semiconductor inspection, alignment, pointing, illumination, and the green color source in RGB displays.

The MiniIR™ laser is a new solid-state Snake Creek Lasers product developed in response to customer demand. The laser produces over 250 mW of CW 1064 nm output power in a diffraction-limited beam. This device can be used with standard Snake Creek Lasers heat sinks for 9.0 mm and Model PS-CW-1900 power supply. The output of this laser is circularly symmetric and can be collimated with simple spherical lenses. It competes favorably with ~ 1 micron diode lasers whose output is astigmatic and requires special optics to produce a semi-collimated beam. MiniIR Series is ideal for use in near-infrared illuminators, for performing 1064 nm gain experiments, and for laser system alignment.

Heat Sinks for 5.6 mm MicroGreen Lasers
Model HS1C-5.6MM heat sinkis designed to adapt MicroGreen™ Series laser for mounting into standard laboratory 1” mirror mounts. Convective cooling is sufficient to provide stable laser output performance under normal laboratory ambient conditions.
The rated performance and stability for the MicroGreen™ Series are dependent upon proper heat management. Model HSR2-5.6MM Rectangular Heat Sink is designed to properly hold MicroGreen Series firm and flush against a prepared surface, thus assuring efficient thermal flow from the laser. Natural air convection from the heat sink is sufficient to assure constant and stable operation of MicroGreen lasers.

Heat Sinks for 9.0 mm Lasers
The HS1C-9.0MM heat sink allows a MiniGreen™ laser to be integrated into standard 1” mirror mounts., which provides a convenient method for precise alignment to external optical assemblies. An external fan (not included) is recommended to assist heat convection into air and thereby provide for long-term stable laser operation.
Part Number: HS1C-9.0MM: 9.0mm 1 inch Circular Heat Sink
The rated performance and stability for the MiniGreen™ Series are critically dependent upon proper heat management. Model HSR2-9.0MM Rectangular Heat Sink is designed to properly hold MiniGreen Series firm and flush against a prepared surface, thus assuring efficient thermal flow from the laser. To prevent heat accumulation in the heat sink, it must be positioned in a (forced) airflow or thermally contacted onto a larger heat-spreading volume typically an exterior part of an OEM mechanical design.
