RGB PULSED LASERS – ALPHA SERIES

Geola is probably the only company manufacturing pulsed SLM RGB lasers with coherence length of more than 3 meters.

Since 2001Geola is manufacturing and selling multi-wavelength pulsed lasers based on its patented intellectual property. In 2006 we are excited to release the ALPHA series of improved multi-wavelength pulsed lasers with optional active cavity length control using a thermally controlled rear-mirror for greatly enhanced long-term stability.

The Geola Multi-wavelength Series is a family of compact single oscillator flashlamp pumped Nd:YAG or Nd:YLF lasers producing emissions in the nanosecond regime.

The lasers produce TEM00 near-diffraction limited radiation at a variety of energies, wavelengths and repetition rates. Single Longitudinal Mode operation is provided with a built-in SLM option. Design features include highly stable passive or electro-optically Q-switched ring-cavity and linear oscillators and harmonic generation.

Fundamental lasing is at 1047, 1053 or 1064 nm and at 1313, 1319, 1321 or 1338 nm. The IRRB laser series emits in the deep IR, Red and Blue wavelengths simultaneously (or separately upon request). The IRRGB laser series delivers pulses at 5 wavelengths simultaneously in the deep IR, IR, Red, Green and Blue (or separately upon request). The RGB series emits at 440nm, 532nm and 660nm.

Optional super-Invar resonator mounting is available with multi-point active temperature distribution control giving output energy stability only expected with more expensive diode pumped lasers.

Below are listed various standard laser configurations. In addition to these models custom lasers are available that cover a large parameter space. Amplified systems are available on a custom order basis.
