Light Conversion​​ is​​ happy to announce​​ that the new​​ 2021 product catalog "FEMTOSECOND LASER SYSTEMS FOR SCIENCE" is​​ now​​ available online.

The ER902 µLaser from MegaWatt Lasers is a Q-switched, Diode Pumped Solid-State Laser (DPSSL) with Er:glass as the gain element.​​ 

The laser generates pulses at a wavelength of 1.535 µm with 100 kW peak power and a pulse duration of 4 ns. Typical repetition rate is 10 Hz, but the laser may be operated at kHz rates for a few pulses.

Laser Quantum offers three diode-pumped solid state (DPSS) lasers with a range of output wavelengths designed for​​ laser lithography applications.​​ The gem series is available with​​ 473,​​ 532​​ and​​ 660​​ nm output options.

By using a combination of hermetic sealing and an active fast feedback system, the gem can achieve outstanding levels of power and stability in all output beam characteristics. All three systems have a single traverse mode and their small, compact footprint makes them easy to integrate into larger platforms.

Here are a few examples of some of the amazing microscopy done with Light Conversion lasers and OPAs:

• Functional neuroimaging deep inside a zebrafish brain using three-photon excitation (using OPA ORPHEUS F​​ configuration)

• Live widefield label-free SHG imaging of fruit fly larva (using PHAROS laser)

• 3D structural harmonic imaging of TPPS aggregates (using FLINT laser)

Hot electron relaxation and transport in nanostructures​​ involves a multitude of ultrafast processes relevant for applications in photocatalysis and optoelectronics. Researchers employ time-resolved photoemission electron microscopy (Tr-PEEM) using the​​ PHAROS​​ laser from Light Conversion​​ to image the relaxation of photogenerated hot electrons within InAs nanowires on a femtosecond time scale.
