New All Solid State UV Lasers Offer True CW Output for
Bio Applications
The new Genesis 355 lasers from Coherent Inc. are the first all
solid state lasers to provide true CW output in the ultraviolet (355
nm). Based on the company’s unique, optically pumped semiconductor laser (OPSL) technology, Genesis 355 products are available
with output powers of 40, 60, 80 and 100 m W. As with other
OPSLs, Genesis lasers feature excellent beam quality (M2< 1. 2) and
low noise (<0.5% rms). They have already proven their superior
performance and reliability in extensive beta testing in target bio-instrumentation UV applications, such as flow cytometry and confocal microscopy. Until now, applications for CW ultraviolet lasers have
had to use either legacy gas laser technology or mode-locked solid state
lasers offering only pseudo-CW performance.

Faster and Cheaper: Uniform Illumination at Tilted Surface for
Inspection and Metrology Tools
Most detection tools (e.g. camera systems) for
analysing surface properties have to be located
perpendicular to the inspected surface. Furthermore,
it is necessary to illuminate this surface homog-
enously. Classic homogenizers enable uniform
intensity distribution only in the plane normal to the
light propagation. If both detection and illumination
units are placed orthogonal to the qualifying surface,
they would disturb each other. Thus a new kind of
asymmetric homogenizer is introduced. This is a
micro-lens array consisting of micro-lenses with dif-
ferent profiles. Free form surface of every individual
micro-lens enables a uniform illumination at the tilted surface. LIMO’s standard illumina-
tion tool for tilted homogenization generates 300 x 340 mm2 field at the angle of 55°, in a
working distance of 1. 5 meters, and with inhomogeneity less than 5 percent.

High Power Light Pulse Generator with
Polarization Maintaining Fiber
Berkeley Nucleonics Corp. (BNC) announces the latest developments in precise light
pulse generation. Our Model 6040 with optical plug-ins from 650 nm-1580 nm, now in-
cludes the option for Polarization Maintaining (PM) Fiber Outputs. PM fiber is a technique
used by the source laser manufacturers and the interconnecting fiber manufactures to
optimize the optical throughput of the entire
system. The fiber axis is aligned according to
various keys and results in improved optical
integrity, reductions in loss of optical power
(measured in joules or milliwatts) and support
of a single polarization state. “We chose the
most reliable PM type available, PANDA-PM,
for our optical pulser. Users need signal stabil-
ity, a trademark in the Berkeley Nucleonics
product line,” comments Mark Slattery, ap-
plication engineer.
T564 Digital Delay Generator
Highland Technology has released the T564,
the latest in its series of mini embedded digital delay generators. Starting with an internal
or external trigger, the module produces four
output pulses programmable for delay and
width, with nanosecond-to-second range and
picosecond jitter and resolution. The T564
introduces three unique features to digital
delay generation: “Queued Updates” allow
time settings to be changed without corrupting ongoing timings; a “Train” function allows
multiple pulses to be generated from each
trigger; and the “Frames” feature allows complex delay sweeps and pulse scenarios to be
pre-loaded and rapidly executed, making the
T564 ideal for laser timing, radar simulation
and ultra-high-speed imaging.
