In addition to 248nm operation, Novatex from Lambda Physik (Fort Lauderdale, FL) is also optimized for ArF (193nm) operation. This excimer laser delivers stabilized output energy of 6 mJ at 193 nm. The average output power of up to 6 W at 1 kHz and outstanding long-term stability make this laser ideal for low-pulse energy and high repetition rate micromachining. Reportedly, the laser complies with SEMI S2 standards and feature excellent gas, optical components and tube lifetimes that have been proven by performance. Optics lifetimes of up to one billion laser pulses are achieved by employing a beam shield that can be purged.

The Gator Series diode-pumped solid-state (DPSS) lasers from Lambda Physik (Fort Lauderdale, FL) now incorporate a number of engineering enhancements. The ability to vary the repetition rate from 5 kHz to 15 kHz allows the user to match the laser's repetition rate to varying feed rates during the process. The external trigger capabilities enable the user to sync the laser pulses to the process and control the repetition rate directly through an external trigger signal. The variable output power helps the user to adjust the laser's output power to changing process conditions. The parallel interface simplifies the integration in CNC systems by providing fast hardware control signals for the laser. And the option to switch wavelengths enables the user to toggle between the fundamental wavelength and the higher harmonics wavelengths.

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.
