Photonic Products has announced a lead-free, blue-violet wavelength (405nm) laser diode from Sanyo. The Sanyo DL-5146-152 405nm, 35mW CW (50mW pulsed) laser diode incorporates an internal monitor photodiode which can be utilised to accurately stabilise and control the optical output power.

Ideal for applications where a stable, accurately controlled output is critical, such as in biomedical instrumentation, medical imaging, fluorescence sensing, spectroscopy and microscopy, the DL-5146-152 has also been developed for use in next generation DVD and many other emerging technologies.

Supplied in a 5.6mm package with M type common cathode pin configuration, the Sanyo DL-5146-152 laser diode has a low threshold current of 38mA, typical operating current of 75mA, operating voltage of 5.6V (higher than conventional lasers), threshold voltage of 4.8V, monitoring output current of 0.2mA, laser reverse voltage of 2V and differential efficiency of 0.9mW/mA at a visible wavelength of 405nm. The operating temperature range is 0 degrees Centigrade to +60 degrees Centigrade. Virtually all Sanyo laser diodes are now RoHS compliant.
