FIBER LASERS The fundamental reason is easy to understand: fi ber
lasers offer their users a production laser at the lowest price per watt, with the highest beam quality, the lowest electrical consumption and minimum maintenance. These lightweight compact lasers can be installed in a matter of a few hours

without the need for special mounting surfaces required by many solid-state lasers. Fiber lasers should not be equated with solid-state disk lasers, which are fi ber delivered, as they do not provide the performance benefi ts provided with a true all-fi ber laser. There are several different types of production fi ber lasers operating at 1070 nm with the choice dependent upon the application. These include lasers operating in a con- tinuous mode from 50 to 100,000 W. There are also lasers operating in either a high-peak-pulsed mode and a lower average power, known as QCW lasers—for example, pulses of 20 kW in the pulsed mode and 2000 W in the continuous mode. The third major contributor is an extensive product line
