Photonic Products Ltd has released its thermo-electrically cooled (TEC) blue/violet laser diode modules that incorporate microprocessor-based temperature control electronics for accurate performance.

Aside from temperature control electronics, the modules also incorporate thermo electric cooler, heatsink, and fan to control the temperature between 15C and 25C with a stability of 0.05C.

Accurate temperature control, together with user adjustment of the laser diode drive current, enables the laser to be tuned to a region where mode hopping and rms noise are significantly reduced or eliminated. It also allows improved wavelength/power stability and longer laser diode lifespan.

The laser diode modules produce elliptical output beams and output powers of 1.5mW (375nm), 4mW and 25mW (405nm), and 4mW (440nm). They are designed for use in applications such as industrial inspection, high-resolution printing, biomedical instrumentation, and spectroscopy.
