   abstract = {Autofluorescence based 2-photon microscopy was investigated as a
tool for studying the dynamics of immunological processes in vivo. Nearly
all tissue components were simultaneously visible by autofluorescence and a
nearly complete visualization of tissue architecture was possible. Within
the tissue, immune competent cells like lymphocytes, macrophages and
dendritic cells were visualized in their dynamic interaction with other
cells or surrounding tissues.
Immunological processes were studied in the small intestine and at the
surface of the eye. Excitation and emission spectra of the different mucosal
tissue components were quantitatively determined and a compared to the
respective spectra of endogenous chromophores. It was shown, that by using
only two excitation wavelengths within the tuning range of a Ti:Saphire
laser enterocytes, antigen presenting cells and lysosomes of the small
intestine could be discriminated based on the excitation and emission
properties. By additionally using an intravital nuclear stain, motion of
lymphocytes in the lamina propria and the epithelium of small intestine
villi was quantitatively analyzed. 

2-photon microscopy was also a powerful tool for studying the conjunctiva
and cornea of the eye. Lymphocyte dynamics and uptake of microspheres or
fluorescing heat-inactivated E. coli was followed over time in the
conjunctiva-associated lymphoid tissue of mice. In a different mouse model
of suture induced corneal hem- and lymphangiogenesis, immune cell migration
into lymphatic vessels and luminal transport of individual cells was
observed in vivo.

Autofluorescence based 2-photon intravital microscopy is a valuable tool to
study dynamic immunological processes. While tissue autofluorescence gives a
good overview over all relevant structures and allows for discriminating
different cell types by spectral analysis, the additional combination of
specific staining with external dyes or fluorescent proteins is easily
possible and enhances the potential of the technique further. },

is achieved due to the Bessel beam that preserves its lateral extend over a large depth range. Decoupling the illumination
from the Gaussian detection improves the sensitivity as compared to double passing the ring filter and enables dark field
imaging. Dark field imaging is useful to avoid strong reflexes from the sample's surface that adversely affect the
sensitivity due to the limited dynamic range of high-speed 8bit acquisition cards. Furthermore, Bessel beams exhibit a
self-reconstruction property that allows imaging even behind obstacles such as hairs on skin.
Densely sampled volumes of skin in-vivo with high lateral resolution are acquired at up to 440kHz A-Scan rate. In
addition the possibility of contrasting capillaries with high sensitivity is shown, using inter-B-scan speckle variance
analysis. High-speed imaging is of crucial importance for imaging small details since sample motion artifacts are
reduced and high sampling can be maintained while increasing the B-Scan rate.},

   abstract = {Selective retina treatment (SRT) is a laser based method to treat retinal diseases associated with disorders of the retinal pigment epithelium (RPE) while preserving photoreceptors and choroid. Applying microsecond laser pulses to the 100- 200 strongly absorbing melanin granules inside the RPE cells induces transient micro bubbles which disrupt the cells. Aim of this work is to understand bubble dynamics in clusters with respect to the influence of the adjacent retina. Bubble dynamics were investigated in vitro on porcine RPE. An about 200 μm thick layer of agarose gel was applied to the RPE layer in order to simulate the mechanical properties of retina. Different laser pulse durations from 1 ns (532 nm, Nd:YAG) to 1.7 μs (527 nm, Nd:YLF) were used. The bubbles were investigated interferometrically (fiber interferometer @ 830 nm) and with fast flash photography (25 ns flash duration). Bubble lifetimes were measured. The results show that with retina phantoms the bubble formation threshold was reached at 2.5 times higher irradiation than without retina phantom for 1.7 μs laser pulses. The microbubbles generated with 1 ns laser pulses were almost not influenced by the agarose layer. Irradiation twofold over bubble formation threshold resulted in 3.5 times longer bubble lifetimes for μs and 2 times longer for ns pulse durations, respectively.},

   abstract = {Retinal laser photocoagulation is an established treatment method for many retinal diseases like macula edema or diabetic retinopathy. The selection of the laser parameters is so far based on post treatment evaluation of the lesion size and strength. Due to local pigment variations in the fundus and individual transmission the same laser parameters often lead to an overtreatment. Optoacoustic allows a non invasive monitoring of the retinal temperature increase during retinal laser irradiation by measuring the temperature dependent pressure amplitudes, which are induced by short probe laser pulses. A 75 ns/ 523 nm Nd:YLF was used as a probe laser at a repetition rate of 1 kHz, and a cw / 532 nm treatment laser for heating. A contact lens was modified with a ring-shaped ultrasonic transducer to detect the pressure waves at the cornea. Temperatures were collected for irradiations leading to soft or invisible lesions. Based on this data the threshold for denaturation was found. By analyzing the initial temperature increase, the further temperature development during irradiation could be predicted. An algorithm was found to calculate the irradiation time, which is needed for a soft lesion formation, from the temperature curve. By this it was possible to provide a real-time dosimetry by automatically switching off the treatment laser after the calculated irradiation time. Automatically controlled coagulations appear softer and more uniformly.},

Aim of the work is the detection of obscured large blood vessels in order to prevent unintentional dissection. Based on spectroscopic investigations of the target tissue (liver), a wavelength for the photoacoustic excitation laser was chosen with respect to a high absorption contrast between the vessel and the surrounding liver tissue. An experimental setup featuring a simple liver model is created. Preliminary results show, that vessels with a diameter of 2 mm can be detected up to a distance of 1 mm from the treatment fibre. It is shown, that detection of acoustic waves induced inside liver is feasible over distances higher than 10 cm.},

abstract = {We present a novel frequency-swept light source working at 1060nm that utilizes a tapered amplifier as gain
medium. These devices feature significantly higher saturation power than conventional semiconductor optical
amplifiers and can thus improve the limited output power of swept sources in this wavelength range. We
demonstrate that a tapered amplifier can be integrated into a 
fiber-based swept source and allows for high-speed
FDML operation. The developed light source operates at a sweep rate of 116kHz with an effective average
output power in excess of 30mW. With a total sweep range of 70 nm an axial resolution of 15 μm in air (~11μm
in tissue) for OCT applications can be achieved.},
