177 Air-Cooled Ion Lasers

Product catalog summary

Overview: The document provides detailed specifications and ordering information for Spectra-Physics Air-Cooled Ion Lasers, specifically the Model 177 series. These lasers are designed for laboratory and instrumentation use, offering high beam quality and stability.

Specifications:

Wavelengths: Available in 514.5 nm, 488 nm, and multiline options (458 nm to 514.5 nm).
Output Power: Ranges from 100 mW to 400 mW depending on the model and configuration.
Beam Characteristics: Beam diameter ranges from 0.70 mm to 0.77 mm, with divergence between 0.80 mrad and 0.93 mrad. The spatial mode is TEM00 with M2 < 1.2.
Stability: Power stability at turn-on is >95%, with stability over 2 hours being <±1%. Beam pointing stability is <±10 µrad/±3°C.
Noise Levels: Periodic noise is <3% peak to peak, with broadband noise <0.2% rms (10 Hz–3 kHz) and <0.5% rms (10 Hz–2 MHz).

Applications: These lasers are suitable for a variety of applications including graphics arts, high-speed printing, Doppler velocimetry, flow cytometry, hematology, cell sorting, confocal microscopy, DNA sequencing, Raman spectroscopy, semiconductor wafer inspection, and bacterial analysis.

Operating Requirements:

Cooling: Requires air cooling with specific airflow for the laser head and power supply.
Electrical Service: Voltage requirement is 200–240 AC, with a current of 16 A max and frequency of 47–63 Hz.
Environmental Conditions: Operates within a temperature range of 4–40°C, humidity 0–95% non-condensing, and altitude 0–3000 m.

Ordering Information: The document provides model numbers for different configurations based on wavelength, spatial mode, polarization, and power. It also includes instructions for ordering remote cooling configurations and fans.

The beam quality and stability for which ion lasers are known is offered in single line and multi-line versions, as well as with polarized and unpolarized options. Output powers from 100 mW polarized at 488 nm (single-line) to 400 mW for unpolarized multiline (458 nm to 514.5 nm) are available. The plasma tube is based on technology proven in over 30 years of industrial applications requiring many thousands of hours of reliable operation. The power factor corrected Model 277 power supply (ordered separately) conforms to CE-mark regulatory requirements. The laser can be operated and monitored with external analog control signals, or with the Model 377G Controller (ordered separately).
