The Power Technology Inc. Grande Series is a high-power laser diode module designed for demanding OEM, industrial and scientific applications requiring high optical output in a compact, robust package. Providing up to 20 W of optical power, the Grande platform combines high-intensity laser output with integrated control electronics for straightforward system integration and reliable operation.
The Grande Series is available across a broad range of wavelengths, including 450 nm, 515 nm, 532 nm, 635 nm, 639 nm, 808 nm, 915 nm and 980 nm, with output powers ranging from hundreds of milliwatts to 10 W and beyond, depending on wavelength and configuration. The 532 nm version, for example, provides up to approximately 900 mW, offering a semiconductor alternative to conventional DPSS laser sources at this wavelength.
An integrated microprocessor and LCD display provide real-time information on laser power, drive current and internal temperature, while drive current and bias can be adjusted with 12-bit resolution (4096 steps). This provides precise control of the laser output without requiring a separate external control system. Digital modulation is also available on applicable configurations.
The Grande is supplied with a collimated optical output as standard on many configurations, with beam characteristics selected according to wavelength and power. The modules use a rugged industrial design with passive cooling for the laser and electronics. Typical operating voltages are 5 VDC for red and infrared configurations, while blue and green versions generally require 8 VDC.
With applications spanning machine vision, 3D imaging, materials processing, localised heating, biomedical instrumentation and OEM systems, the Grande provides a flexible high-power laser source where stable CW operation and straightforward integration are important.
