Description
The LHCVN Series from OSI Laser Diode Inc. represents a cutting-edge solution in the realm of hybrid laser diodes, specifically engineered for pulsed operations. These laser diodes are renowned for their high peak power emission, making them a reliable choice for a variety of demanding applications. With a peak emission wavelength centered around 905nm, the LHCVN Series ensures precise and consistent performance, ideal for specialized uses where accuracy is paramount.
Designed with efficiency in mind, the LHCVN Series operates at low voltage, which is a significant advantage over traditional discrete laser drivers. This capability allows for much narrower pulse widths and faster rise times, providing enhanced performance without the need for high voltage requirements. The series is compatible with all OSI Laser Diode, Inc. standard MOCVD laser diodes and can be optimally driven using commercially available MOSFET drivers, ensuring seamless integration into existing systems.
The LHCVN Series is housed in a hermetic TO5 package, which offers increased efficiency while maintaining a compact form factor. This makes it an ideal choice when space and weight are of primary concern, such as in aerospace or portable devices. Additionally, the robust design ensures reliable operation across a broad range of temperatures, making it suitable for various environmental conditions. The LHCVN Series is RoHS compliant, aligning with global standards for environmental safety and sustainability.
When handling the LHCVN Series, it is crucial to adhere to safety precautions due to the Class 3B laser classification. Proper care should be taken to avoid exposure to laser light, which can be harmful to the human eye. Furthermore, electrostatic discharge (ESD) precautions are essential to prevent damage to the diode lasers during handling. For optimal performance, the use of a MOSFET driver is recommended to trigger the hybrid laser diode effectively.
