High-power direct-diode lasers have emerged as a competitive option for applications like cladding, welding and heat treating. Stuart Woods of Coherent explains why the basic construction and ...

Laser diodes, the devices that illuminate telecom fiber-optic cables, require light-current-voltage (L-I-V) measurements during production. These measurements let you characterize a laser diode's ...

Laser diodes can destroy themselves in a few nanoseconds, so testing the response and stability of a feedback-stabilized laser-diode driver can be expensive. The simulator circuit in Figure 1 shows a ...

Laser cutting and engraving technologies have become essential tools across a wide variety of different industries, from manufacturing, art and small businesses. These technologies use laser beams to ...
