VECSEL Benefits |
VECSEL Uses |
|
| Good Beam Quality | High power (Watt) | |
| External mirror makes transverse mode control robust | NIR lasers around 1 µm could replace cw diode pumped Nd lasers | |
| Intracavity nonlinear Optics (possible) | (visible) for projection displays and to replace Ar+ lasers | |
| Increased beam diameter over VCSEL | Pump source for communication amplifiers | |
| Compact | Green, blue and near-UV sources | |
| Efficient… 40% optical-optical efficiency has been demonstrated (more should be possible) |
Low power | |
| Several wavelengths are available in low and high power configurations | digital imaging, flow cytometry, drug discovery, DNA sequencing, & wafer inspection | |
| compact, efficient for chem lab on a chip |
Optically and Electrically Pumped VECSELS
Optically pumped VECSELs have a simple cavity. Optical pumping is convenient, efficient and can be made compact.
