LOWER ENERGY SLM Nd LASERS

The Geola G-Mini series is a family of compact single oscillator flash lamp pumped Nd:YAG or Nd:YLF lasers producing emissions in the nanosecond regime.

G-Mini series

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 either 1064, 1053 or 1047nm. Optional frequency conversion to the 2^nd, 3^rd and 4^th harmonics gives accordingly: 532,526, 523.5, 355, 351, 349, 266, 263, and 262 nm.

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.

Optional LabWindows^TM based PC control of laser functions is available with output energy plot.

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