The Mamba Green from Coherent is a frequency doubled, diode-pumped solid-state laser that offers a combination of high output power and reliability for a range of materials-processing tasks.
The Mamba Green delivers more than 325W of output at 532mm (at 10kHz), and the laser's integrated doubling crystal shifter and field-replaceable gain modules provide an expected operating lifetime of more than 25,000 hours.
In addition, the Mamba Green is said to enable high process throughput and flexibility through the use of Pulse Ondemand.
This feature stabilises laser-output characteristics in both single-shot and burst-mode operation, and also includes first-pulse equalisation, making it possible to utilise every pulse produced by the laser.
Coherent said the Mamba Green is an ideal laser source for a number of industrial and scientific applications, including surface texturing, cutting, drilling, marking and engraving of metals such as steels and aluminium.
In these applications, the Mamba Green is claimed to provide high throughput (for example, 1,000 holes/min of 0.25mm diameter on 800um-thick aluminium).
The laser is also said to be useful for a variety of semiconductor-processing tasks, including low-temperature polysilicon (LTPS) recrystallisation for display manufacture, dopant activation in the fabrication of IGBT semiconductors and CMOS devices, and annealing for CMOS sensors.
The Mamba Green can even be used for pumping Ti:Sapphire amplifiers, where it offers high power and high repetition rate output.
