MID-IR-2 RF-Excited FrequencyDoubled CO2 WaveGuide Laser
The MID-IR-2 Advantage The Coherent-DEOS MID-IR-2 RF-excited, frequency-doubled CO2 waveguide laser system brings short-pulse, high pulse-repetitionfrequency (PRF) capability to the scientific/ aerospace/industrial user at mid-IR wavelengths (4.6 µm –5.4 µm). Ruggedized for the most severe environments, it is the standard of the industry for demanding field applications. The pump laser of the MID-IR-2 features an efficient folded-resonator design contained within an all-metal housing. Metal seals insure both long operational and shelf lifetimes. This CO2 short-pulse pump laser also incorporates a patented intracavity, electro-optic modulation technique that produces short optical pulses with widths of less than 15 nanoseconds, Full Width Half Maximum (FWHM) and a PRF variable from 0 Hz to 100 kHz. The pulsed output produces multi-kilowatt peak power optical pulses which are efficiently frequency doubled, yielding a rated average power of 2W at 100 kHz PRF. An option also enables the same unit to operate in a continuous-wave (CW) mode with an average output power that exceeds 100 milliwatts. The MID-IR-2 laser system consists of two modules: 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, cavity-tuning PZT and a patented high-damage-threshold frequency doubler, all in a sealed metal housing. The rack-mountable C/PS module contains the control electronics, RF power supply, associated DC power supplies, safety interlocks and key switch. The two modules are connected with a rugged cable system available in standard or custom lengths. The user can interface with the laser system through controls provided on the front panel of the C/PS module, enabling the laser head to be remotely located. The all-solid-state RF power supply, contained within the C/PS module, can be operated either in a CW mode or in an enhanced-pulse modulated mode, allowing the user to obtain higher peak-power performance. The system also includes an inte-grated DC supply, allowing the MID-IR-2 to be operated from standard 200 - 240 VAC input power. The superior performance of the MID-IR-2 laser is demonstrated in the high output per unit volume obtained under technology protected by Coherent-DEOS patents.
