Developed over years of testing under severe operating conditions, anddesigned to be operator-friendly, the GEM Select 50 offers high beam quality and stabilityto meet the most demanding requirements.

The clean layout of the laser’s rear panel offers immediate access to the interlock control,the key-operated on-off switch, and status indicators.

The superior performance of the GEM product line is demonstrated in high outputpower per unit volume, obtained with the parallel resonant, distributed inductance excitation scheme integrated into all GEM lasers. The optional PZT tuning mirror enablesfine frequency control about line center.

The GEM Select 50 is engineered, as are all our laser products, to deliver years of reliableservice.

Additional features provide flexibility for your unique requirements. With the optional grating tuner, over 60 discrete rotational lines are attainable over the 9.2 to 10.8 micronregion, with the strongest lines delivering over 40 watts. The optional PZT cavity-tuningmirror makes the GEM Select 50 an ideal source for CW heterodyne laser radars.

GEM Select 50GEM Select 50 Specialty Laser Options

Various options can be added to thebaseline Coherent GEM Select 50Specialty laser to fill a wide range ofapplications. If you require assistance in selecting options, provide us withyour requirements and we will workwith you to set the specifications anddesign.

Tunable WavelengthThis option allows wavelength tuning from 9.2 to 10.8 microns.A high-resolution grating and a calibrated, manually-driven differentialmicrometer permit accurate selectionof individual rotational lines. Outputpower with this option is specified as>40W at the strongest line; typical representative output powers can befound in the table.

Fixed WavelengthThis option is recommended whenfixed wavelength operation is required(specify wavelength when ordering,factory set). Output power is depen-dent on rotational line selected, withstrongest lines producing greater than40 watts. (See table for typical power.)

Full-Range 9 µm OperationThis option optimizes performance in the 9P rotational branch (9.4 to 9.8 µm) and allows operation over theentire wavelength range from 9.2 to10.8 µm.

PZT Cavity TuningThe PZT cavity-tuning option allowsfine frequency control within any givenrotational line by adjustment of thecavity length. The typical tuning rangeis ±50 MHz about the center line. Usersupplies 0 to 10V signal to adjust thecavity length.

Variable Output PowerThe variable output option allowsadjustment of output power from itsmaximum value to under 50% of fullpower. The actual adjustment range is dependent on the operating wave-length. Input power is also reduced.

Autonomous Frequency/Amplitude ControlThis option allows the laser to operatewith ultra-stable frequency and ampli-tude output. The use of an integratedmicroprocessor servo-loop system provides automatic control of thelaser’s output frequency and amplitudeby applying a ~1 MHz peak-to-peakdither to the cavity PZT, in conjunctionwith phase-sensitive-detection forfeedback control.

External Modulation InputThis option allows the user to operatethe laser in pulse or “enhanced pulse”mode via an external TTL input afterthe initial 5-second start-up delay. (Thisoption cannot be used in conjunctionwith the Variable Power Option.)

Internal PointerThis option provides an internal, visibleaiming beam that is collinear with thelaser’s output beam.

Coherent - DEOS CO2 Laser RF-Excited, Frequency-Doubled

MID-IR-2RF-Excited Frequency-Doubled CO2 WaveGuideLaser

The MID-IR-2 AdvantageThe Coherent-DEOS MID-IR-2 RF-excited,frequency-doubled CO2 waveguide laser systembrings short-pulse, high pulse-repetition-frequency (PRF) capability to the scientific/aerospace/industrial user at mid-IR wave-lengths (4.6 µm –5.4 µm). Ruggedized for themost severe environments, it is the standard ofthe industry for demanding field applications.

The pump laser of the MID-IR-2 features anefficient folded-resonator design containedwithin an all-metal housing. Metal seals insureboth long operational and shelf lifetimes. ThisCO2 short-pulse pump laser also incorporatesa patented intracavity, electro-optic modulationtechnique that produces short optical pulseswith widths of less than 15 nanoseconds, FullWidth Half Maximum (FWHM) and a PRFvariable from 0 Hz to 100 kHz. The pulsedoutput produces multi-kilowatt peak poweroptical pulses which are efficiently frequencydoubled, yielding a rated average power of 2Wat 100 kHz PRF. An option also enables the sameunit to operate in a continuous-wave (CW)mode with an average output power thatexceeds 100 milliwatts.

The MID-IR-2 laser system consists of twomodules: A laser head module and a control/

power supply (C/PS) module. The laser headmodule includes the gain cell, resonator optics,EO modulator driver system, cavity-tuning PZTand a patented high-damage-thresholdfrequency doubler, all in a sealed metal housing.The rack-mountable C/PS module contains thecontrol electronics, RF power supply, associatedDC power supplies, safety interlocks and keyswitch.

The two modules are connected with a ruggedcable system available in standard or customlengths. The user can interface with the lasersystem through controls provided on the frontpanel of the C/PS module, enabling the laserhead to be remotely located.

The all-solid-state RF power supply, containedwithin the C/PS module, can be operated eitherin a CW mode or in an enhanced-pulsemodulated mode, allowing the user to obtainhigher peak-power performance. The system alsoincludes an inte-grated DC supply, allowing theMID-IR-2 to be operated from standard 200 - 240VAC input power.

The superior performance of the MID-IR-2 laseris demonstrated in the high output per unitvolume obtained under technology protected byCoherent-DEOS patents.

Coherent - DEOS CO2 Laser Short-Pulse, RF-Excited

EOM-10Short-Pulse RF-ExcitedCO2 WaveGuide Laser

The EOM-10 AdvantageThe Coherent-DEOS RF-excited EOM-10laser system brings short-pulse, high pulse-repetition-frequency (PRF) capability to thescientific/aerospace/industrial user in acompact package. Ruggedized for the mostsevere environments, it is the standard of theindustry for demanding field applications.

The EOM-10 features an efficient folded-resonator design contained within anall-metal housing. Metal seals insure both longoperational and shelf lifetimes. This short-pulseunit uses a patented intracavity, electro-opticmodulation technique to produce short opticalpulses with widths of less than 15 nanosecondsFull Width Half Maximum (FWHM) and a PRFvariable from 0 Hz to 100 kHz. The pulsedoutput produces multi-kilowatt peak poweroptical pulses, yielding a rated average powerof 10W at 100 kHz PRF. An option also enablesthe same unit to operate in a continuous-wave(CW) mode with an average output power thatexceeds 20 watts.

The EOM-10 laser system consists of twomodules: A laser head module and a control/power supply (C/PS) module. The laser head

module includes the gain cell, resonator optics,EO modulator driver system and cavity-tuningPZT in a sealed metal housing. The rack-mountable C/PS module contains the controlelectronics, RF power supply, associated DCpower supplies, safety interlocks and keyswitch.

The two modules are connected with a ruggedcable system available in standard or customlengths. The user can interface with the lasersystem through controls provided on the frontpanel of the C/PS module, enabling the laserhead to be remotely located.

The all-solid-state RF power supply, containedwithin the C/PS module, can be operated eitherin a CW mode or in an enhanced-pulsemodulated mode, allowing the user to obtainhigher peak-power performance.
