Tunable Diode Lasers

Grating stabilized diode lasers in Toptica's proprietary pro technology can now be equipped with laser diodes from 370 nm to 1770 nm. The TA pro, a master oscillator power amplifier system, provides up to 1.5W output. Frequency converted lasers offer UV, green or yellow light, e.g. at 589 nm with 20W (Guide Star) or 2W (Na laser cooling). Other recent developments include fiber amplified tunable diode lasers, cw lasers at 190 nm, and high speed locking electronics for linewidth narrowing below 1 Hz. moreNov. 04, 2009

Developing MALDI Imaging Technology for Cancer Profile

Normal and diseased tissues are complex mixtures of different cell populations. A better understanding of protein expression changes that occur during 
diseases needs sensitive and specific technologies for each of these cell types. Mass spectrometry based tissue imaging (MALDI-MSI) is a newly developed technique, allowing the visualization of proteins, peptides, lipids and small molecules directly on thin sections cut from fresh frozen or fixed paraffin embedded tissues. more
