Industrial Fiber Optics has created a very unique and special laser for the educational market. The ML 825 is a small-form factor, solid state green laser. It uses cutting edge technology housed in a durable metal package standard to the ML 800 product line. The laser's bright green emission wavelength is achieved with an eye-safe CDRH Class II rating. The enclosure measuring 18.1 x 3.3 x 4.7 cm also contains rechargeable batteries. It's among the smallest combined laser-power-supply packages on the market.

The brightness, optical power stability, good beam quality, and pointing stability make this laser an excellent choice for general-purpose lab and educational work. The ML 825 is suitable for basic optical experiments as well as those involving interferometry, scattering, diffraction and refraction. It is also ideal for presentations and demonstrations because of its battery (cordless) operation and handheld size.

The ML 825 utilizes the latest in laser technology - Diode Pumped Solid State (DPSS). A high-efficiency near-infrared laser diode optically stimulates a crystal to lasing, and the lasing output is frequency-doubled (wavelength halved) in another crystal medium to generate a bright green emission at 532 nm. Output collimating and filtering optics complete the conversion to deliver a high quality, green laser beam. Although this process is indirect, use of high-efficiency low-cost infrared laser diodes (as used the telecommunications industry) more than make up the difference between typical direct and indirect modes. In addition, it is easy to control the optical output from laser diodes and therefore easy to control the laser's output power level. The result is an stable, efficient and economical green emission laser source.
