|
| INNOVATION
Developed compact, reliable, solid state microchip-based laser transmitter for satellite laser ranging featuring:
- Low-energy microchip laser producing very short pulses.
- Efficient, transversely diode-pumped, multipass Nd:YVO4
amplifier for two order-of-magnitude increase in pulse energy.

ACCOMPLISHMENTS
- Achieves laser energy, pulsewidth, and repetition rate goals of SLR 2000 and meets current eye-safety standards.
- Uses passively Q-switched microchip laser technology which provides low maintenance and failsafe reliability.
- Transmitter prototype was developed, delivered, and tested in NASA GSFC SLR 2000 satellite ranging system.
|
COMMERCIALIZATION
- Commercial customer is funding further development for application to metrology product.
|
GOVERNMENT/SCIENCE APPLICATIONS
- Ruggedized, conductively cooled, fully automated SLR 2000 Field transmitter based on this technology is now under development in NASA Phase III Contract.
