FTSS355-300

Product catalog summary

Product Overview: The FTSS 355-300 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 355 nm, delivering single pulses with a duration of less than 1.7 ns and a pulse energy greater than 300 μJ.

Optical Specifications: The laser features a TEM00 spatial mode with a beam divergence of less than 2.5 mrad and a beam ellipticity of less than 2:1. The beam diameter at the laser exit is 400 ± 150 µm. It achieves a peak power of 180 kW at 20 Hz and supports a pulse repetition rate of 1 to 80 Hz, with closed-loop control available for 5 to 40 Hz. The polarization ratio is greater than 100:1, vertical, with long-term pulse energy stability within ±5% over six hours and pulse-to-pulse stability of less than 3% rms.

Safety and Emissions: The laser is classified as Class 3B / IIIb according to IEC 60825-1:2014. Residual emissions are less than 0.5 mW at 1064 nm (Class 3R) and less than 0.1 mW at 532 nm (Class 2).

Electrical and Interface Details: The laser consumes less than 90 W of electrical power and operates on a line voltage of 100-240 V AC 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 to 38 °C. The laser head dimensions are 217 x 65 x 45 mm.

Options and Accessories: Available options include an SMA-connector for fiber, synchronization signal output, manual or electrical beam control, wavelength switching, and an upgrade to a 1 kHz repetition rate. Additional accessories include an external telescope, heat sink with fan, and a stand-alone system with safety features.
