Laser welding with CO2, fiber and various types of solidstate lasers is a well established process currently utilized in a wide range of industries and applications. However, recent technological developments in high power diode laser technology have expanded the capabilities of laser welding, as well as changed its cost characteristics. As a result, diode lasers are poised to replace tradition...

Up to 16 W output power has been obtained using spectral beam combining of two 1063 nm DBR-tapered diode lasers. Using a reflecting volume Bragg grating, a combining efficiency as high as 93.7% is achieved, resulting in a single beam with high spatial coherence. The result represents the highest output power achieved by spectral beam combining of two single element tapered diode lasers. Since s...

Rapid prototypings using direct selective laser sintering (SLS) ofmetal/ceramic powders have a great potential for design and fabrication of near net shape of metal/ceramic parts. At presents CO2, Nd:YAG and Excimer are the only possible solutions for the heavy duty manufacturing applications. At the University of Connecticut, researchers advanced the concept of rapid prototyping and other desk...

OBJECTIVES Fluoride therapy is important for control and prevention of dental caries. Laser irradiation can increase fluoride uptake especially when combined with topical fluoride application. The objective of this study was to compare the effects of CO2 and diode lasers on enamel fluoride uptake in primary teeth. MATERIALS AND METHODS Forty human primary molars were randomly assigned to four...

The actual market volume of high-power lasers for manufacturing is dominated by diffusion cooled CO2 laser systems at the multi-kW range and lamp pumped Nd:YAG laser systems at the kW range. Substituting the lamps by diodes the Nd:YAG laser in rod design entered the market as diode pumped solid state laser of the first generation. With output powers up to 6 kW the diode pumped rod is used in in...

Background and Aim: Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to ...

Lasers are widely used in various manufacturing processes. In order to achieve sustainable production, it is important reduce the environmental impact caused by laser operation. One major improvement step from gas lasers diode lasers.

At the recent Photonics West and Optical Fiber Conferences, companies presented many new products, ranging from mechanical products to instruments to complex laser systems. As a product engineer, there is nothing quite like the feeling of standing in the booth, talking to potential customers about the product You’ve designed or built. But the real success happens when customers buy the product ...

There are now many applications for visible and UV continuous wave lasers in the tens to hundreds of milliwatts power range, covering e.g. life sciences, metrology and inspection. Originally these were dominated by ion and HeCd metal vapor lasers due to their early availability. However, these sources are characterized by numerous well-known practical deficiencies (e.g., large size, electrical ...

It is quite common to note chronic inflammatory Gingival overgrowths during and/or post orthodontic treatment. Sometimes the overgrowths may even potentially complicate and/or interrupt orthodontic treatment. With the introduction of soft tissue lasers these problems can now be addressed more easily. Amongst many LASERS now available in Dentistry DIODE LASERS seem to be most ideal for orthodont...
