Battery power for Laser Drivers and Temperature Controllers – can the laser diode driver and temperature controller be powered by batteries directly?
Wavelength manufactures different versions of the WLD3343 and WTC3243, including models designed for battery-driven operation. It is important that you verify the operational configuration using the Safe Operating Area (SOA) Calculators for each product.
The WLD3343HB laser driver is designed to operate with an input voltage of 3.3 V to 6 V, whereas the non-HB version operates across an input voltage of 5 V to 12 V. The lower input voltage range of the WLD3343HB is optimized for more efficient battery-driven operations.

Likewise, the WTC3243HB operates with an input voltage range of 3.3 V to 8 V, compared to the input voltage range of 5 V – 30 V of the WTC3243. Use the Temperature Controller SOA calculator: Safe Operating Area Calculator for Temperature Controllers
