Custom Pulsed Lasers
Unlike many companies, we can design custom pulsed lasers according to your exact requirements or modify our standard lasers in order to satisfy your needs.
The G-MINI series are family of compact flash lamp or DPSS 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 produces TEMoo near diffraction limited radiation at a variety of energies, wavelengths and repetition rates.
Energy range is 2-50milliJoules, pulse duration – 1-50 nanoseconds, standard repetition rate – 1-50Hz. Fundamental lasing is at either 1047, 1053, 1064, 1079, 1313, 1319, 1338 or 1342 nm.

Description
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. All 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 accomplished with multi-point active temperature distribution control of laser breadboard giving output energy stability only expected with more expensive compact diode pumped lasers.
The G-MINI series pulsed lasers usually are being manufactured for particular client application, maximum fulfilling laser functionality and its adaptability in each specific case.
Fundamental lasing is of wide choice and frequency conversion to the 2nd, 3rd and 4th harmonics gives variety of lasing wavelengths.
