Model PL2210 actively mode-locked diode-pumped Nd:YAG laser from EKSMA Co. (Vilnius, Lithuania) delivers up to 2 mJ, greater than 50-ps pulses at 1 kHz repetition rate with energy stability at 1064 nm better than two percent. The mode-locking technique is all solid-state without any dye used. A master oscillator and built-in regenerative amplifier design ensure cost-effectiveness and hands-free laser operation. Optical jitter of 0.06 ns in respect to sync pulse enables reliable synchronization of the laser with other equipment.

The A700 from Meta Vision Systems (St-Laurent, Quebec) scans a high-intensity laser spot across a joint to enable seam tracking on shiny surfaces. According to the manufacturer, the sensor looks slightly ahead of the weld torch while an on-board linear camera, scanned in sync, captures a 3D cross section of the joint that the system software uses to determine its exact position before and during welding. The sensor can be used with the company's Laser Pilot MTR for robot applications and with the VistaWeld system on automated welding machines. The system can be optimized and programmed for a variety of joint profiles, depths and sizes.

High Power Laser Cables from CeramOptec (East Longmeadow, MA) exhibit performance up to 5 kW and transmission from 350 to 2500 nm. Compatible with all laser systems, the laser cables are available with fiber core diameters from 300 to 600 µm for stock sizes, though others are available upon request. According to the company, the laser cables are protected against bucking at both ends of the fiber and they feature laser beam protection (LBP) to protect the fiber from laser illumination. With FOP-D, FOP-N and other connectors available, the laser cables feature tight bend radii as small as 250 mm. Additional options include fiber-break detection using an integrated FiberSideLine system that automatically discontinues laser delivery if a break in the fiber is detected.
