Record and play the new blue-violet semiconductor laser diode “SLD3237VF” with Blu-ray Disc. The pulse output is up to 400mW and also supports the new specification “BDXL” for high-capacity Blu-ray discs.
The 400mW output power blue-violet semiconductor laser diode is the industry’s first product. By increasing the power, the output margin is ensured, and the range of optical components such as lenses and prisms can be expanded. In addition, by expanding the selection range of optical components, the degree of freedom in designing hardware can be improved.
In order to achieve a high output power of 400 mW, it is necessary to prevent the end face of the laser resonator called catastrophic optical damage (COD) from being dissolved by the heat of the laser, and to improve the crystal quality of the GaN crystal constituting the material to ensure high reliability. Technological innovation. This product has newly developed a surface coating material and a film forming method, which has successfully improved the light output value of a 300 mW semiconductor laser which has previously caused COD.
SLD3237VF with 400mW output and SLD3237VFR with 350mW output on the right
In addition, in order to improve the crystal quality, a MOCVD (organic metal chemical vapor phase growth) crystal growth apparatus optimized for the production of a constituent material, a GaN-based material, has been newly developed. The MOCVD apparatus can crystallize a plurality of substrates at a time, and can cope with an increase in demand for semiconductor laser diodes for Blu-ray discs in the future. Further, a process and a process apparatus capable of ensuring high production efficiency in the wafer processing step after the crystal growth step have been developed.
The SLD3237VF is housed in a 5.6mmφ standard package. The operating temperature range is 0 to 85 °C. In addition, the “SLD3237VFR” packaged in a 3.8mmφ small-diameter package for thin IT driving is also available. The product has a pulse output of 350mW and an operating temperature range of 0 to 90 °C.

Precautions:
This component is sensitive to static electricity. Do not take anti-static measures. Do not touch the laser tube body directly by hand. In addition, this product must have a qualified drive circuit to work normally. The voltage of different power is the same, but the working current is different. The drive current needs to be controlled within a safe range, otherwise it will affect the life. The store has its own development of boost constant current circuit with soft start and reverse connection protection.
