Various options can be added to the base unit COHERENT-DEOS GEM Select 100 Specialty laser to fill a wide range of applications. If you require assistance in selecting options, provide us with your requirements and we will work with you to establish the specifications and design. PZT Cavity Tuning The PZT cavity-tuning option allows fine frequency control within any given rotational line by adjustment of the cavity length. The typical tuning range is ±30 MHz from the center line. User supplies 0 to 10V signal to adjust the cavity length. Variable Output Power The Variable Output Option allows adjustment of output power from its maximum value to under 50% of full power. The actual adjustment range is dependent on the operating wavelength. This adjustment also reduces the input power. External Modulation Input This option allows the user to operate the laser in pulse or enhanced pulse mode via an external TTL input after the initial 5-second start-up delay (This option cannot be used in conjunction with the Variable Power Option). Internal Pointer This option provides an internal, visible aiming beam that is co-linear with the laser s output beam.

GEM Select 50 GEM Select 50 Specialty Laser Options FEATURES Tunable or Fixed Wavelength Full-Range 9 µm Operation PZT Cavity Tuning Variable Output Power Autonomous Frequency/ Amplitude Control External Modulation Input Internal Pointer Various options can be added to the baseline Coherent GEM Select 50 Specialty laser to fill a wide range of applications. If you require assistance in selecting options, provide us with your requirements and we will work with you to set the specifications and design. Tunable Wavelength This option allows wavelength tuning from 9.2 to 10.8 microns. A high-resolution grating and a calibrated, manually-driven differential micrometer permit accurate selection of individual rotational lines. Output power with this option is specified as >40W at the strongest line; typical representative output powers can be found in the table. Fixed Wavelength This option is recommended when fixed wavelength operation is required (specify wavelength when ordering, factory set). Output power is dependent on rotational line selected, with strongest lines producing greater than 40 watts. (See table for typical power.) Full-Range 9 µm Operation This option optimizes performance in the 9P rotational branch (9.4 to 9.8 µm) and allows operation over the entire wavelength range from 9.2 to 10.8 µm. PZT Cavity Tuning The PZT cavity-tuning option allows fine frequency control within any given rotational line by adjustment of the cavity length. The typical tuning range is ±50 MHz about the center line. User supplies 0 to 10V signal to adjust the cavity length. Variable Output Power The variable output option allows adjustment of output power from its maximum value to under 50% of full power. The actual adjustment range is dependent on the operating wavelength. Input power is also reduced. Autonomous Frequency/ Amplitude Control This option allows the laser to operate with ultra-stable frequency and amplitude output. The use of an integrated microprocessor servo-loop system provides automatic control of the laser s output frequency and amplitude by applying a ~1 MHz peak-to-peak dither to the cavity PZT, in conjunction with phase-sensitive-detection for feedback control. External Modulation Input This option allows the user to operate the laser in pulse or enhanced pulse mode via an external TTL input after the initial 5-second start-up delay. (This option cannot be used in conjunction with the Variable Power Option.) Internal Pointer This option provides an internal, visible aiming beam that is collinear with the laser s output beam.
