aeroGAIN-ROD High Power Ytterbium Rod Fiber Gain Modules

aeroGAIN-ROD module is the ultimate in fiber amplification for pulsed lasers with a power handling previously only available in solid state configurations. With a 3300 µm2 mode field area and high pump absorption, the aeroGAIN-ROD module offers up to ten times the performance of our aeroGAIN-FLEX and -BASE models.

The excellent mode quality and easy coupling makes the aeroGAIN-ROD module an ideal gain medium for high power amplifiers. The rugged aluminum body makes the module easy to handle and mount for both OEM integration and scientific laboratory setups. Integrated water cooling with quick coupling ensures efficient thermal management and a long maintenance-free lifetime of thousands of hours. The pump light is guided by our proven airclad technology, with high reliability, high damage threshold and large NA. The modules comes standard with high power AR coated end-caps.
