Lamp Pumped Nd:YAG Lasers Roadmap Statement

SPI Lasers (“SPI” or “the Company”)

Press Release: 2nd October 2015



Starting in December 2013, the SPI Lasers facility in Rugby (formerly JK Lasers) commenced the wind down of its CW Lamp Pumped Solid State Lasers (CW LPSSL). The total market size for LPSSL’s continues to decline, with alternative, more efficient and lower operating cost technologies and products available. 

As of today 15th April 2015, SPI Lasers has completed the acquisition of JK Lasers based in Rugby (UK), to enhance its high power Fiber Laser portfolio.

With almost 100 employees and annual sales of 17.6 million euros, JK Lasers is one of the world's leading manufacturers of high-power Fiber Lasers for industrial use; their acquisition helps SPI Lasers to strengthen their position as a leader in the Fiber Laser market.

New research has revealed that demand in the global industrial fiber laser market is set to explode in the next four years, soaring by more than 21%. The report, available from Sandler Research, relied on input from industry experts and in-depth market analysis and concluded that the field is set to expand by as much as 21.4% CAGR by 2018.

JK Lasers announce their involvement as a core industrial partner in the EPSRC’s new Centre for Innovative Manufacturing in Laser Based Production Processes. The aims of the CIM are to exploit the unique features of laser light to unlock manufacturing innovation, delivering ground-breaking industrial impact in key areas of the UK economy.

During the last six years, JK Lasers has developed and introduced to the market a range of medium power (50 W – 1 kW) and high power (1 kW – 3 kW) fiber lasers for cutting, welding and fine drilling applications. This success means changes now for our Lamp Pumped Solid State Laser (LPSSL) Nd:YAG product ranges: JK Lasers plans to phase out the CW LPSSL Product Line by the end of 2015, as outlined in the attached PDF. Please contact This email address is being protected from spambots. You need JavaScript enabled to view it. for further details.

JK Lasers will be exhibiting at Laser World of Photonics this year as the exhibition celebrates its 40th anniversary.  The show runs alongside the World of Photonics Congress and saw great success in 2011 when the Messe Münchenhosted 1,075 exhibitors and over 27,000 visitors.

3kW Fiber Laser Launched by JK Lasers

A powerful 3kW fiber laser has been launched by global industrial laser manufacturer JK Lasers, part of the GSI Group. The new addition to the company’s Watt to kiloWatt fiber laser range will help enhance manufacturing productivity by processing thicker section metals at faster speeds and to higher standards.

Fiber lasers are a precision material processing tool used for a diverse range of applications from the manufacture of small, intricate medical devices to flat sheet cutting thick section metals. To ensure these parts are manufactured to the highest possible standards, the laser operator precisely controls the intensity on the target. Parameters such as pulse energy and the temporal profile are easily controlled.

The processing advantages of fiber lasers will be showcased by JK Lasers when it makes its debut appearance at The Battery Show, Detroit, between 13 and 15 November.
