Geola

Geola's BlueBird series pulsed lasers emit Gaussian TEM₀₀ SLM radiation at 440 nm and are particularly designed for holography and scientific applications.

The Digital Thermo Control (DTC) nonlinear crystal oven models DTC-A, DTC-B, DTC-C offer excellent temperature stability of ±0.1 K in the temperature range 30–71 °C.

The DTC–A model ovens is suitable for crystals with apertures 2 × 2, 3 × 3, 4 × 4 or 5 × 5 mm. The DTC-B is for crystals with apertures 6 × 6, 8 × 8, 10 × 10, 12 × 12 or 15 × 15 mm. Still larger nonlinear crystals are supported by the DTC-C oven.

The new DTC-HT model is designed for high operation temperature (up to 220 °C) NCPM applications.

On request, we can manufacture ovens for crystals with aperture up to 60 × 60 mm or even larger.

Temperature settings are stored in the internal memory of the thermo controller and can be easily changed in the Geola ThermoTool software provided together with DTC oven, which is connect via USB cable. After the temperature is set and DC 24 V power is applied, the oven works in a completely autonomous regime, and the DTC does nott require any cable connection with the PC.

The MID14-24 is precise motorized iris diaphragm, which is adjustable either mechanically or on a PC with an intuitive graphical user interface. Our unique design has aluminum blades forming a square diaphragm, always remaining centered to an internal SM1–threaded hole during size tuning. The adjustment step size is ≈10 µm.

The square Iris diaphragm is also designed to be compatible for either stand-alone (MID14-24) or 60 mm standard (for example Thorlabs) Cage System (MID14-24C).

Geola Digital specializes in designing and manufacturing vacuum cells for pulsed laser applications. These cells can be produced with a central pinhole (VSF) or without one (VC). For instance, the VSF or VC models are used to prevent air breakdown when employing a Kepler-type refocusing telescope.

Geola Digital manufactures high efficiency pump chambers for various active elements such as Er:YAG, Er:YLF, Nd:glass, Nd:KGW, Nd:YAG, Nd:YLF, Nd:YVO₄, Yb:YAG, etc.

We offer laser pump chamber models GAP for 6 mm, 10 mm, 12 mm, 20 mm and 25 mm rods. All pump chambers contain efficient glazed Al-ceramic reflectors made for standard flash lamps and are constantly used in our own laser manufacturing.

We are manufacturing these series of high energy lasers:

• The GxJ series lasers produce single output near-diffraction limited single-longitudinal mode (SLM) super-Gaussian radiation in the nanosecond regime from 1 to 15 J per pulse (fundamental harmonics).
• GxJ TWIN series lasers produce dual output near-diffraction limited single-longitudinal mode (SLM) super-Gaussian radiation in the nanosecond regime from 2 to 20 J per pulse (fundamental harmonics).

Geola has been specializing in the design and manufacturing of machinery for display and security holography for over 20 years. Their applications includes digital printers, industrial replication machines, various master hologram originators, and analogue studios.

Geola offers compact flash-lamp-pumped Nd:YAG, Nd:YLF or Nd:YAP lasers generating pulses in the nanosecond regime. These lasers are based on a single longitudinal mode linear, telescopic or ring type master-oscillator design. A single longitudinal mode module is installed that narrows the spectral linewidth and thus provides long pulse coherence lengths. The lasers produces TEM₀₀ near diffraction limited radiation with a variety of pulse energies, wavelengths and repetition rates.

The central piece of Diode-Pumped Solid-State (DPSS) lasers or laser amplifiers are laser gain modules. Geola Digital can provide such gain modules based on Vertical Cavity Surface Emitting Laser (VCSEL) pumping engine technology. They provide a uniform gain distribution, high pumping efficiency and a long lifetime. We have both water-cooled and passively cooled gain modules. Typical air-cooled DPSS gain modules are applicable for Nd:YAG master oscillator or Nd:YAG laser amplifiers.

Customized laser gain modules can be also designed and provided on request.

Geola Digital manufactures various optomechanics such as translation stages and other position equipment, which are used for various laser and photonics applications.

Geola is manufacturing various SBS cells only using non-toxic liquids. Therefore, our cells can be also used for medical or OEM equipment. We can provide custom designs with different cell length and mounting options.

Geola offers phase-conjugating cells which are suitable for pulse compressors achieving very high peak intensities. This is useful for applications like material processing, laser machining, and certain scientific experiments.

Geola speciales in TEM₀₀ and SLM pulsed lasers from sub-ns pulse duration to >10 J per shot.

Geola can provide various pump chambers containing either flash lamps (FL) or laser diodes (LD). All pump chambers (gain modules) provide a uniform gain pumping distribution, high pumping efficiency and a long lifetime of the pump sources. We have three types of pump chambers (gain modules):

• air cooled VCSEL pumped pump chambers
• water-cooled VCSEL pumped pump chambers
• water-cooled flash-lamp pumped solid state pump chambers

We can also provide customized pump chambers.
