Idk about the specific diode in your devices, but guessing it won’t hurt to do some tests. Adafruit provides voltage supply specs for the laser pointer they sell, 2.8-5.2V:
It would be a fair assumption that your lasers can also handle a tad over 5V. Current when driving leds near Vf can be a bit unpredictable, but I’m not sure if laser diodes behave the same. If you have a multimeter with current measuring abilities, you could measure draw to make sure it won’t be too much for your existing 5v source.
