By Tony Hoult Nobody would disagree that real change is occurring in the laser industry. In the broadest context, what is happening is a shift from the conventional technique of assembling lasers using free space optical components to a technique based on splicing together fiber based components. It is now very widely accepted that this […]

High Speed Spindle Balancing with Pulsed Fiber Lasers
By: Marek Mamczur – Dynamic Laser Solutions and Jack Gabzdyl – SPI Lasers Today’s high speed production drills in PCB board manufacture operate at speeds in excess of 250,000rpm. The spindle shafts in these devices need to be individually balanced by very selective removal of material to ensure that, in operation, they run true. Any […]
Remote Laser Welding of Zinc-Coated Sheetmetal Component in a Lap Configuration Utilizing Humping Effect
By: Hongping Gu and Boris Shulkin Stronach Centre for Innovation (SCFI) With the advancement of high power fiber delivery lasers, remote laser welding becomes a reality and furthermore cost reduction on a new laser system in recent years drives adoption of laser welding process into production lines. Remote laser welding takes the advantages of less […]

Thermal Lensing Compensation Objective for High Power Lasers
By: Michael Scaggs Athermalization of focusing objectives is a common technique for optimizing imaging systems in the infrared where thermal effects are a major concern. The athermalization is generally done within the spectrum of interest and not generally applied to a single wavelength. By applying athermalization techniques to a laser system, a significant reduction in […]
