The VCSEL and possesses the accumulation micro lens VCSEL array which is used for the semiconductor laser pumping solid state laser system

摘要

The vertical cavity surface emission laser which possesses power and the beam feature which are improved (VCSEL) the device. The VCSEL device includes the array of one VCSEL or VCSEL. Each VCSEL has the accumulation micro lens which corresponds, can install the heat sink on device side of the VCSEL device. Heat dissipation is improved by the heat sink, power feature of the output laser beam of the VCSEL device is improved with that. With the micro lens or maikurorenzu array, to focus more simply and compact it is possible the output laser beam of the VCSEL device. As for the VCSEL device, it can use for the various optical systems, that power and the focus feature which are improved, low power, low offer the laser system of cost with the compact.
