Description

Extremely compact, All-in-One 20~100-mJ-level (pls. specify), nanosecond Nd:YAG laser head with integrated control electronics and laser diode current driver and integrated FIBER BUNDLE coupling port (customer-specified fiber bundle to be used, pls specify).

 

This extremely small laser head is suited for space-constrained and handheld applications (total weight <2.5 kg). The laser can be integrated in the user’s setup and just needs to be mounted onto a sub-mount capable of taking the head away during operation to avoid heat accumulation. The user simply provides an external 24-28 VDC power supply and a pulse trigger (TTL) if externally triggering is desired.

 

Benefits: In contrast to existing flash-lamp-pumped Nd:YAG technologies, this laser is laser-diode-pumped and the conductively cooled laser diode stack is included in the laser head. Not only the compactness but also lower electrical power consumption, lower weight, maintenance-free operation and improved beam quality, divergence and focusability are achieved and result in improved application results.

 

Applications: The compactness and low weight enable applications that were not possible with existing flash-lamp pumped technologies, including portable applications and other applications with critical space and/or weight constraints. Applications of this compact laser model include PA (Photoacoustic Imaging) and nanosecond illumination.
