Photonic Products, a UK optoelectronics device manufacturer and laser diode specialist, has introduced a lead-free, blue-violet wavelength (405 nm) laser diode from Sanyo. The Sanyo DL-5146-152 405-nm, 35-mW CW (50-mW pulsed) laser diode incorporates an internal monitor photodiode that can be used to accurately stabilize and control optical output power. Ideal for applications such as biomedical instrumentation, medical imaging, fluorescence sensing, spectroscopy and microscopy, the DL-5146-152 was also developed for use in DVD and other emerging technologies. Supplied in a 5.6-mm package with M-type common cathode pin configuration, the Sanyo DL-5146-152 laser diode has a low threshold current of 38 mA, typical operating current of 75 mA, operating voltage of 5.6 V (higher than conventional lasers), threshold voltage of 4.8 V, monitoring output current of 0.2 mA, laser reverse voltage of 2 V and differential efficiency of 0.9 mW/mA at a visible wavelength of 405 nm. The operating temperature range is 0 to 60 degrees C. Virtually all Sanyo laser diodes are now RoHS compliant.
