Water cooling high-power diode laser side pumped gain modules

The pumping module is completely maintenance-free. It incorporates a Nd:YAG laser rod that is efficiently pumped by arrays of long life laser diode bars, and delivers excellent gain uniformity and lensing performance. Such modules are applied for OPO,nanosecond/picosecond laser amplifiers and high gain pulsed pumping laser systems etc...

The diode pumped laser module has quickly become an industry standard; thousands of these workhorse components are in use around the world.  They have proven themselves to be a reliable, high-performance component in DPSS laser systems.  It is a second-generation model that includes new features that make it even easier to integrate and service.  The Diode-Pumped Laser Module is offered at power levels up to 500 Watts in a simple, compact, and affordable package. 

 

The module is an ideal building block in the development or production of high power rod laser systems, conversion of existing lamp-based laser designs to diode-pumping

The pump module is completely maintenance-free. It incorporates a Nd:YAG laser rod that is efficiently pumped by an array of long life laser diode bars, and delivers excellent gain uniformity and lensing performance. It is ideally suited for multimode applications such as laser cutting and marking, and can also provide high beam quality for more precise micro-machining and scientific applications. 

 

The module is driven by low voltage electronics.  Cooling of the laser is accomplished with a simple recirculating water chiller running on filtered water, eliminating the need for deionized water systems.
