FQSS266-50

Product catalog summary

Product Overview: The FQSS 266-50 is a diode-pumped passively Q-switched solid-state laser designed for applications in biology, biomedicine, chemistry, and analytics. It operates at a wavelength of 266 nm, delivering single pulses with a duration of less than 1.1 ns and a repetition rate of 1 to 100 Hz, with pulse energy exceeding 50 μJ.

Optical Specifications: The laser features a TEM00 spatial mode with an M² value of less than 1.5, beam divergence of less than 3.0 mrad, and beam ellipticity of less than 1.5:1. The waist diameter is 800 ± 200 µm, located approximately 110 mm inside the laser head, and the beam diameter at the exit is also 800 ± 200 µm. The peak power is greater than 45 kW, and the polarization ratio is over 100:1, vertical. Long-term pulse energy stability is maintained within ± 3% over six hours, and pulse-to-pulse stability is less than 1% rms.

Electrical Specifications: The laser consumes less than 70 W of electrical power and operates on a line voltage of 100 - 240 V AC (50-60 Hz) or 24 V DC. It includes interfaces for RS 232 and USB connections.

Operational Conditions: The laser requires a warm-up time of less than 15 minutes and operates within a temperature range of 18 - 38 °C. The laser head dimensions are 217 x 65 x 45 mm.

Options and Accessories: Available options include synchronization signal output, manual or electrical beam blockers, wavelength switch between 266 nm and 532 nm, external telescope, and attenuators. A stand-alone system option is also available, which includes a key-switch, heat sink, and manual shutter, compliant with CDRH standards.

Safety and Compliance: The FQSS266-50 laser is classified as Class 4 / IV according to IEC 60825-1:2014 standards. Residual emissions are less than 0.5 mW at 1064 nm (Class 3R) and less than 0.1 mW at 532 nm (Class 2).
