Liquid Cooling a Laser for System Optimization
cooling systems, cold plates, and heat exchangers are a few of the cooling technologies used in laser systems' liquid cooling loops. Low-powered lasers, such as small helium-neon or argon-ion lasers, may not require cooling or may come with their own cooling fan, which is generally sufficient. Some...

The Progress of Industrial Laser Marking (.pdf)
Laser markers were once bulky machines that required constant maintenance to replace coolant and lamps. They consumed enough energy to power a small household and were used mostly to mark product packaging and metal components. The design and capabilities of marking systems have come a long way...

Effective Monitoring of Cooling Towers
coupling inserts were completely worn out. This was causing looseness in the drive shaft. Most of the rubber was completely missing on a couple of the inserts. After replacing the inserts and doing a laser alignment, the vibration levels returned to normal. We also experienced vibration problems...

A Cooling Tower Adventure in Alignment (.pdf)
they were handled with a laser motor via a 60 jackshaft with single flex plane couplings. alignment system. at each end. The fan enclosure consists of a fiberglass shell. The cooling tower in question has a 12' Marley fan. constructed around a wooden framework, located outside. whose gearbox is coupled...

Hot tips for cool enclosures
dust from entering the enclosure. Chillers can be used to cool enclosures as well as fluids like oil and water in laser-cutting applications and machine-tool industries. Cooling capacity ranges from 3,500 up to 410,000 Btu. Today's industry mantra is to design products that are smaller, faster...

, and the working time or shelf life of a biological sample or laboratory reagent can be increased by keeping the substance at an optimal temperature. Instruments such as DNA cyclers, tunable laser diodes, and thermal-stress analyzers all require a capacity for cycling an object or sample through a range...

MICRO:Product Technology News (May '99)
A laser cutting tool for flat-panel display glass makes high-quality cuts without creating particles. While glass has traditionally been cut using a mechanical scribe-and-break process that causes fragmentation, edge chips, and microcracks that may generate particles, the laser technique uses...
