Mul-T-Lase is a multifunctional medical laser system designed for the aesthetic dermatology and plastic surgery. Mul-T-Lase presents an entire spectrum of advantages and unique options:

Base Platform + Removable Laser Handpiece concept

Universal Use. Several laser handpieces have been developed to cover various dermatological issues. Mul-T-Lase will help you to choose the correct applicator for your treatment. This will insure a complete absorption of a given wavelength by the skin chromophores. and the correct penetration of laser emission into the tissue
Economy. Save space and reduce your cost costs by purchasing only the handpieces for the clinical applications that are really relevant to you.
Upgradeability. Upgrade your system any time in the future when needed
Speed. There are two connective sockets for laser handpiece connections at Mul-T-Lase. Switching between left and right handpieces is virtually instantaneous.

User-friendly interface

LNF-series flashlamp pumped OEM laser heads

alex — Sat, 22 Oct 2011 16:41:01 +0000

Description

LNF series flashlamp-pumped pulse OEM laser heads operate in free-running mode with wavelengths 755, 1064, 1320, 1440, 1540, 2108 and 2940 nm and are designed for using in medical and industrial laser systems.

Laser rods and flashlamps from the best manufacturers provide high efficiency and reliability. The use of stainless-steel pump chambers with glazed ceramic reflectors provides high efficiency and reliability. Laser heads are designed with the attention to cavity stability. Special design of mirror holders with adjustment screws blocking and base plate made from non-tensioned aluminium increase the mechanical and temperature stability of laser heads.

QBD-BT-series bench-top Pockels cell drivers

victor — Sat, 22 Oct 2011 05:43:36 +0000

Description

QBD-BT-series consist of ten Pockels cell drivers differ with their output voltage range (up to 6.0 kV) and operating scheme (see also How to order? section).

Operating scheme may be either (pull down scheme (= normally on) or push up scheme (= normally off). Scheme should be predefined at the time of order.

High repetition rates and fast transition times are additional benefits of QBD-BT-series Pockels cell drivers.

Performance

For 5.0 kV modification continuously operated in internal synchronization mode we warrant the performance table as follows:

External synchronization mode shows usually a little higher performance.

In the burst-mode (= short time operations) performance is increasing approximately twice and may achieve 100 kHz value at low operating voltages and load capacitance.

High load capacitance decreases the performance.

QBU-BT-series bench-top Pockels cell Drivers

victor — Sat, 22 Oct 2011 05:12:50 +0000

Description

QBU-BT-series consist of five Pockels cell drivers differ with their output voltage range (see also How to order? section) and covering range up to 6.0 kV.

Modules allow operations in three different modes (pull down scheme (= normally on),push up scheme (= normally off) and external synchronization mode (= repetition of external low voltage signal)) and therefore suit ideally for the laboratory usage.

High repetition rates and fast transition times are additional benefits.

Performance

For QBU-BT-5020 continuously operated in internal synchronization mode we warrant the performance table as follows:

External synchronization mode shows usually a little higher performance.

In the burst-mode (= short time operations) performance is increasing approximately twice and may achieve 100 kHz value at low operating voltages and load capacitance.

High load capacitance decreases the performance.
