This laser series is a line of solid-state electrically pumped diode lasers. Diode lasers achieve population inversion by applying a sufficiently strong voltage across the p-n junction of the diode to break the Fermi level of the diode into two quasi-Fermi levels. Population inversion occurs when the difference between the two resulting quasi-Fermi levels is greater than the band gap of the material. Compact and self-contained, this laser emits a pure TEM00 beam with diffraction limited performance and a typical M2 of 1.05. Available in UV (375 nm), violet (405 nm), blue (440 nm), red (635 nm, 660 nm, and 685 nm), and NIR (780 nm and 830 nm). With variable power options, these modules are ideal for demanding applications, such as metrology, photoluminescence, printing, illumination, scanning, inspection, particle counting, and a variety of biomedical applications. These turnkey lasers maintain outstanding optical performance over a broad temperature range, guaranteeing minimal power fluctuations and virtually eliminating high frequency noise. Its OEM version has the world’s smallest OEM controller with power consumption less than 5 Watts. It has been qualified for use in some of the most demanding high-end instruments, with deployments in the tens of thousands of units. The 375 nm, 405 nm and 440 nm systems replace bulky, expensive gas ion lasers for biomedical and fluorescence applications, without sacrificing beam quality.

RMS Noise Specs

graph
The Trek™ can be operated in a wide temperature range (10oC - 35oC), with a stable and quiet laser output power at most wavelengths. The Trek™ has a proven history of RMS noise stability less than 1.0%. The combination of excellent beam characteristics (such as mode quality, low divergence, and brightness), makes the Trek™ laser series suitable for beam focusing, as well as for long distance beam positioning.

Digital Modulation / External Trigger Specs

graph



Using the TTL modulation option, the laser can be digitally pulsed in on/off mode up to 20 kHz with a modulation depth greater than 100:1. With a rise/fall time of less than 4 μs, the TTL signal can be used in conjunction with the trigger signal of your detection system to control your measurement cycle and integration time. TTL modulation is ideal for Raman spectroscopy, fluorescence spectroscopy, and other applications where the source and the detector need to be precisely triggered.

Analog Modulation Specs

graph



With analog modulation (AM), the laser output power is controlled by applying an arbitrary 0 - 5 V input signal from a function generator. Using the AM option, the laser can be modulated up to 1 kHz with a modulation depth greater than 100:1.
