Ruggedized Lasers

Model ML301HD and Model MIL301HD ruggedized laser diode modules from Bea Laser Inc. (Elk Grove Village, IL) withstand vibration, chemical, impact, and dust conditions. Available in red or green laser beam output, these units are suitable in applications for metal forming equipment, punch presses, and heavy-duty saws where alignment, targeting, and positioning are of prime importance. Each liquid-resistant unit consists of the laser module, a molded connectorized cable assembly, and a DNN rail mount power supply. Output power is at 5mw with wavelengths of 650nm for the red, and 532nm for the green. Operating voltage is at 5VDC @ 30mA for the red and 300mA for the green.

LED Driver

Linear Technology (Milpitas, CA) offers the LT3598, a 45V, 2.5MHz DC/DC boost mode converter designed to operate as a constant current LED driver for up to sixty white LEDs. The LT3598 can drive up to six strings of LEDs, each with up to ten 30mA white LEDs in series, while delivering efficiencies up to 90%. Its multichannel capability makes it ideal for medium sized TFT-LCD backlighting applications, and its input voltage range of 3V to 30V makes it ideal for automotive and industrial applications. The LT3598 offers 1.5% LED current matching to insure uniform brightness of the display.

Laser Apparatus

Mobius Photonics (Santa Clara, CA) has been awarded U.S. Patent #7,443,903 for a new laser apparatus that has multiple synchronous amplifiers tied to one master oscillator. This fiber-based architecture scales up average power for integration into high throughput machine tools without sacrificing reliability. Conventional diode-pumped, solid-state lasers are incapable of this flexibility and scalability. The laser apparatus is ideal for cost-sensitive applications such as solar cell processing, PCB manufacturing, or display manufacturing.

Damage-Resistant Mirrors

Saint-Gobain Crystals (Hiram, OH) has introduced high reflectors optimized for use with q-switched, solid-state lasers (Nd:YAG, NdYVO4, and Nd:YLF) operating in the near infrared and visible spectrum (1064nm, 1053nm, 532nm). The coatings on the beam delivery optics are designed to withstand high peak fluences and deliver over 99.5 percent reflectivity. The standard versions of these high-power, solid-state laser reflectors are supplied on 1 inch (25.4mm) or 2-inch (50.8mm) diameter fused silica substrates. They have a specified flatness of λ/10 (at 633nm) and a laser grade surface quality of 10-5 (over an 85 percent clear aperture).

Dispersion Control Modules

OFS (Norcross, GA) has announced new additions to its FemtoCompTM Modules line of dispersion control technologies for ultra-short pulse lasers. The modules address the difficult-to-match, third- and fourth-order dispersions of commonly used grating compressors. There are four new FemtoComp Modules in addition to the original 1μm wavelength version: two pulse-stretcher modules for either the 1 or 1.55μm wavelength range, a polarization-maintaining module in the 1μm wavelength range, and a module for the .8μm wavelength range.
