LOWER ENERGY SLM Nd LASERS

 

The Geola G-MINI series is a family of compact single master-oscillator Nd:YAG, Nd:YLF or Nd:YAP lasers producing emissions covering fundamental spectrum from 1047 to 1342 nm.


G-Mini series
 

 The G-MINI series is family of compact flash lamp or laser diode pumped Nd:YAG, Nd:YLF or Nd:YAP lasers producing emissions in the nanosecond regime. Lasers are based on Single Longitudinal Mode linear, telescopic or ring type master-oscillator design. Single Longitudinal Mode module is installed that narrows spectral linewidth and provides long pulse coherence length. The lasers produce TEM00 near diffraction limited radiation at a variety of energies, wavelengths and repetition rates. Design features include a highly stable passively or EO Q-switched oscillators. SuperINVAR based resonator framing is acomplished with multi-point active temperature distribution control of laser breadboard giving output energy stability only expected with more expensive compact diode pumped lasers.


Fundamental lasing is of wide choice and frequency conversion to the 2nd, 3rd and 4th harmonics gives variety of lasing wavelengths.
