Diode-pumped narrow linewidth multi-kW metalized Yb fiber amplifier
We investigate high brightness pumping of a multi-kW Yb fiber amplifier in a bi-directional pumping configuration. Each pump outputs 2 kW in a 200 μm, 0.2 NA multi-mode fiber. Gold-coated specialty gain fibers, with 17 m MFD and 5-dB/meter pump absorption, have been developed. The maximum fiber amplifier output power is 3.1 kW, limited by multi-mode instability, with 90% O-O efficiency 12 GHz ...
متن کاملDiode-pumped 1 kW Q-switched Nd:YAG rod laser with high peak power and high beam quality.
We have demonstrated high-peak-power generation at 1 kW average power by applying an acousto-optic Q switch to a quasi-cw diode-pumped Nd:YAG master oscillator power amplifier. We achieved a maximum peak power of 2.3 MW by driving the Q switch in burst mode. The average repetition rate was 6 kHz. The corresponding beam quality was M2 = 9.
متن کاملLaser cutting of metal laminates: analysis and experimental validation
Laser cutting has been investigated for a number of aluminum±synthetic laminates, newly developed materials for the aeronautic and automotive industry. The materials consist of alternating aluminum and synthetic layers. It is shown that these materials can be cut at the same speed as homogeneous aluminum alloys, although some damage on the synthetic layers has to be accepted. Based on these exp...
متن کاملHigh Speed Thin Metal Cutting using Fiber Laser Technology
There are several methods available for precision cutting of thin metals less than 0.06-inch thick used for these applications, which include materials such as stainless steel, titanium, nickel, and aluminum. The major options, lasers, electric discharge machining (EDM), water-jet, and chemical machining each have a role to play. However, precision fiber laser cutting technology is now emerging...
