The CadiYAG is a compact, diode-pumped solid-state professional laser. It is designed for maximum reliability.
Several versions of the CadiYAG are available. The basic model operates at 1064 nm with various power levels between 10 W and 120 W cw.
The Q-switched models generate strong pulses with a repetition rate between 0 and 50 kHz. The maximum average power of the Q-switched version is 90 W. Therefore, the peak power of a single pulse is well above 100 kW.
This high peak power combined with the uniform beam quality is ideal for many industrial applications, such as marking, cutting, engraving, trimming, etc.
With frequency doubling, the Q-switched CadiYAG versions deliver strong pulses at 532 nm. The maximum average power is 45 W. The repetition rate can be chosen between 0 and 50 kHz.
The frequency doubling stage uses reliable and durable industrial crystals. This is a precondition for long and maintenance free operation intervals.

The VersaDisk is a solid-state laser with exceptional performance. It produces high output power with a perfect Gaussian intensity distribution. The M² value is < 1.1. This differentiates VersaDisk from all other solid-state industrial lasers as those favour either high power or high beam quality.
The novel pumping scheme of the laser professional crystal grants high pumping efficiency while it maintains an especially easy optical cavity of the laser itself. This
straight-forward design concept provides stable operation over extremely long periods without any re-alignment.
VersaDisk is not only a laser, but represents a technology platform for future expansion and enhancement of its performance. It can be specifically tailored to theneeds of any application or for general purposes in the research laboratory.

The RBA GOLD is the third generation of diode-pump solid state modules. Complementing the popular RB Plus family of modules, the RBA Gold has all the same features as the RB Plus with an additional integrated circuit board that protects against all major premature failure mechanisms. The RBA Gold features build-in sensors for the monitoring of the diode array and ambient temperatures, humidity as well as warnings for coolant leaks, over current and over voltage problems. These CEO proprietary protection features set a new precedent in the professional laser industry enabling OEM's to protect their investments and minimize risk. In addition every RBA Gold pump module comes standard with an unrivaled 3-year warranty.
The RBA Gold family of DPSS modules is offered at power levels up to 100 Watts in a simple, compact, and affordable package. It is also an ideal building block in the development or production of medium power rod laser systems, conversion of existing lamp-based laser designs to diode-pumping, or retrofit of existing arc lamp hardware to provide more stable and reliable operation.
The pump module is completely maintenance-free. It incorporates a Nd:Yag laser rod that is efficiently pumped by long life laser diode manufacturer bars, and delivers excellent gain uniformity and lensing performance. It is ideally suited for multimode applications such as laser marking and can also provide high beam quality for more precise micro-machining and scientific applications.
The RBA Gold 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. |
