Innovative 705nm Laser Diode for Biomedical Measurement

Photonic Products, the UK opto-electronics device manufacturer and laser diode specialist, is delighted to be the authorised distributor of the first 705nm semiconductor laser diode from Opnext. This is an innovative laser diode from Opnext; a lasing wavelength of 705nm is pioneering and unique, totally new to the market.

The Opnext HL7001MG / HL7002MG laser diode is designed for use in biomedical applications such as blood analysis and endoscopy which benefit from this infrared laser diode’s high reliability, low operating current requirement and high output power. The lasing wavelength of 705nm at 50mW offers high permeability for living tissue and low absorption of haemoglobin and water.

The Opnext HL7001MG / HL7002MG laser diode has optical output power of 50mW CW (typ) at a lasing wavelength of 705nm, low operating current of 75mA, low operating voltage of 2.5V, LD reverse voltage of 2V, PD reverse voltage of 30V, a low threshold current of 30mA and monitoring output current of 0.15mA. The operating temperature range is -10 degrees C to +60 degrees C.

Supplied in a 5.6mm package with 3P-type common cathode pin configuration, (HL7001MG) or 1N pin configuration, (HL7002MG), this is a single longitudinal mode Opnext laser diode with a built-in monitor photodiode.

The 5.6mm package size is ideal for small, energy-efficient medical sensor equipment and low-power optical measurement applications and enables a reduction in the size of current biomedical measurement equipment whilst improving the quality.

“We are proud to add this cutting-edge laser diode to our range of Opnext laser diodes,” said Damon Cookman, Photonic Products Ltd. “Opnext continues to innovate and produce high quality laser diodes, and Photonic Products is delighted to be an authorised distributor”.
