High Power Low Noise Laser

The attractive features of low noise green microchip lasers are its low noise performance, high PER and compact size. However, due to

the limitation of previous crystal design, stable low noise output cannot be achieved at high power level, especially above 100mW. While

at the same time, a high power green laser with stable low noise is desirable for many applications.

In 2014, Suwtech developed new technology to re-design our multi-layer crystals (patent approved) to achieve > 10K hours lifetime.

Based on its low noise, high power and good beam quality, High Power Low Noise Lasers are the ideal solutions for a wide range of

applications including life science and laser display.

BMU Series

Direct Laser Diode Module is a kind of laser module with point output. Its advantage of mini size is ideal to be used in the pocket

devices. It can realize very wide operating temperature from 0°C to 60°C without TEC. The power stability is more stable based

on its APC function. It is designed for volume producible with excellent reliability and stability.

BMU1E Series

II-VI BMU1E multimode laser diode module series has been designed to provide high power and reliability required for pumping

next generation solid-state and fiber lasers, and for direct applications. The module includes a multimode laser diode chip with

E2 front mirror passivation that prevents Catastrophic Optical Damage (COD) to the laser diode facet even at very high power

levels. The coupling process allows for high output powers that are very stable with both time and temperature。

BMU Series

BMU3E Series

II-VI's multimode single emitter based laser diode module has been designed to provide an increased power output enabling fiber

laser and direct system manufacturers to generate higher powers with fewer modules, allowing for more compact pump configurations,

greater pump block efficiency and simplification of packaging. Its compact design reduces the footprint of fiber laser pump stages The

module includes multimode laser diodes with E2 front mirror passivation that prevents Catastrophic Optical Damage (COD) to the laser

diode facet even at very high power levels. The laser diodes are connected in series to allow for fast current switching. The module

includes a feedback protection filter that protects the laser diodes from harmful fiber laser wavelength feedback light.

II-VI's new multimode laser diode modules based on single emitter have been developed to provide a wavelength-stabilized

performance over wide operating temperature and output power ranges. With increased spectral brightness, the wavelengthstabilized modules will enable ultrafast fiber lasers to operate with shorter pulses and achieve higher performance stability and

improve their productivity as well.

These modules have the same outer appearance with legacy BMU products, succeed the existing advantages and adapt to mature

mass production process.

BMU Series

BMU High Power Module

II-VI’s new high power fiber-coupled diode pump module platform will offer up to 300W output through a multimode fiber. With more

emitters integrated, this single emitter based platform offers increased brightness. The high brightness pump enables fiber laser

manufacturers to generate higher pump power levels using fewer modules, allowing them to increase pump block efficiency, design

more compact pump configurations, and simplify their packaging. A novel optical scheme delivers light into the fiber with high coupling

efficiency, and a controlled under-filled NA along with a cladding mode stripping feature, which allows customers to increase reliability

and reduce losses at the combiner. A compact housing offers superior thermal management. Integrated design and fewer

components enable high volume with high manufacturing efficiency with high consistency in module-to-module performance.
