RGB PULSED LASERS – ALPHA SERIES |
| Geola is probably the only company manufacturing pulsed SLM RGB lasers with coherence length of more than 3 meters. |
| |
The RGB-ALFA series is family of compact master oscillator flash lamp pumped Nd:YAP , Nd:YAG and Nd:YLF lasers producing emissions in the nanosecond regime. Design features include a highly stable passively or EO Q-switched oscillator and frequency conversion to the second and/or third harmonics by means of various NLO crystals.
The lasers produces Single Longitudinal Mode and TEM00 near diffraction limited radiation at a variety of energies, wavelengths and repetition rates. Laser models with multimode flat-top output is also available.
In addition to constituting highly versatile laboratory tools all ALFA series lasers are rigorously designed to meet the high stability standards required for scientific and technological applications.
