Stradus laser diodes

Vortran Laser Technology has introduced its Stradus family of laser diode modules, capable of delivering digital modulation at 200MHz. The Stradus product line is available in popular wavelengths suitable for biomedical, R&D, and laboratory applications, including 660nm at 100mW, 642nm at 110mW, the newly-introduced 488nm at 50mW, 445nm at 40mW, 405nm at 100mW, and 375nm at 16mW.

Key features of the diode modules include a typical M² of 1.25 and circularity of more than 90 per cent. All wavelength models offer low RMS noise (less than 0.1 per cent from 10Hz to10MHz – except 0.2 per cent for 488nm). Beam dimensions are 1.3mm diameter for all wavelengths and the pointing stability is less than 5µrad/ºC. The Stradus family also offers good power stability (<0.5 per cent for 24 hours).

All Stradus diode laser modules are compatible with both USB and RS-232 interfaces. The devices are intended for applications in medical diagnostics, flow cytometry, defect analysis, and other laboratory applications.

Vortran’s recently introduced Stradus 488nm diode laser module features an output of 50mW. It is designed as an affordable alternative to standard, high-power-output diode-pumped, solid-state (DPSS) lasers which are commonly used in flow cytometry and microscopy applications. This innovative model features digital modulation up to 200MHz, with analog modulation at 500KHz.
